Iconia W500 Screen lockups with Brazos 4 build

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Boot and logon
2. Use tablet for 20 minutes, then screen blanks out and returns with a pixel 
crash of some sort. 
3. Have to hard reboot to resolve, and then the issue repeats itself. 

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
Using the brazos 4.0 build on an Iconia W500

Please provide any additional information below.

After using the 4.0 build on my W500 for a couple days, I sadly have to report 
that I get screen lockups that require a hard boot to resolve. (Same problems I 
had with the version 3 build)   They seem to happen after about 20 minutes of 
use,  almost like a screen saver or dimmer is kicking in that blows out the 
video driver. However, I've verified that all screen saver settings are 
disabled in the settings app.     

During the initial boot,  I get the following error before the Android Logo 
Appears:

"Host Bridge Windows Conflicts with Video Rom"  

along with some memory address space information. 

Very frustrating because the 4.0 build is fantastic for that 20 minutes of use.

I also have this issue. Also seeing "Address space collision" on startup.
Not sure if it is related but the graphics card shares the main memory with 
384mb.
The VGA bios version is ATI VGA ver012.036.000.029.041128.
I have updated to the latest BIOS.

This is a great peace of programming. It boots fast, is very responcive and is 
low on resource use. I have 30gb of disk space compared to the 15gb when 
windows is installed. 

If there is anything you need to solve this issue please message me and i will 
help immediatly.

Kind regards

Daniel

Hi all

I have managed to solve the "ROM address issue" by doing this:

_host_bridge_window_conflicts_with_Adaptor_ROM

Kind regards

Daniel,
Thanks for finding this.   I made the change in the boot file and while it does 
stop the address space collision error during boot, it has not stopped my W500 
from generating a pixel screen crash after 15 to 20 minutes of use.        Have 
you found that this change resolves your screen crash issues?

I have the same problem. Although I have updated the new bios, the problem 
still occurred. On the other hand, no sound, can not play movie (e.g. youtube, 
pps etc.)

There's another active thread with the w500 that's getting more feedback than 
this one and has some recent fixes, specifically with loading an updated video 
driver that improves the screen crash issues somewhat, but not completely.   
Here's the link:

Hi! My final installation of ICS Android on Acer IconiaTab W500:
- Prepare SD Memory (I am using 4g SD, I tried 16g SD, but it's very slow) for 
Android System
- Prepare USB Memory (I use 2g USB) for installation
- Download "unetbootin-windows-563.exe"
- Download "android-x86-4.0-amd_brazos-20111209.iso"
- Insert SD and USB Memory
- Format SD and USB Memory with FAT32
- Release the SD Memory
- Run unetbootin, ISO-> 
Select->"android-x86-4.0-amd_brazos-20111209.iso"->select USB Memory drive->OK
- Shut Down the machine
- Boot W500 and go to bios setup, select the USB Memory for the first boot
- Reboot again with pressing "power button and Windows key" for USB boot
- When u see the menu, select the Install Android (no enter), insert SD Memory, 
Now you can <enter>
- No need to format the SD again, Just install the Android
- Install grub, no need to create fake usb
- Wait for a few minutes ... 
- Shut down the machine when u see the installation completed and a menu
- Release the USB
- Boot the windows
- Edit the menu.lst in grub folder on SD (use WordPad on windows) 
- Add a command "pci=nocrs"  (avoid space collision), listed as below:

title Android-x86 2011-12-09
    kernel /android-2011-12-09/kernel  pci=nocrs  quiet root=/dev/ram0 androidboot.hardware=amd_brazos acpi_sleep=s3_bios,s3_mode SRC=/android-2011-12-09
    initrd /android-2011-12-09/initrd.img
- Save
- Shut down the machine
- Now u can boot the android system with pressing "power button and Windows 
key" from SD boot.

Eyerying Fine. Multi Touch Ok, Wifi Ok, Fast
Unfortunately, the screen still crashes periodically, No sound, No Video movie 
playing
Anybody can solve the above problems clearly?  especially the the screen crash 
problem.

Just loaded the 12/25 brazos build.    Sound works, wifi works, and Touch 
works. Nice!  Display still flashes periodically, but screen crashes are much 
less frequent.    So definite progress on the screen issue, but the lack of a 
functional browser is really unfortunate. I've tried several browsers without 
success.

Followed instructions in comment 6 and everything is working EXCEPT touch and 
browser.  Is there something else I have to do to enable touch?

Did U install on Acer W500? 
The muti touch function works on my W500 (I tried installation many times).
Pls ref to the comments above.
We mentioned sound works, wifi works, browser not works.
The android system is only for my son playing games.
If u want to use the browser, u can install "Android-x86 2011-12-09".
But the sound not works.

see the comments

Try booting with the tablet undocked and see if touch works.  If it does you 
can redock it after boot to get leyboard/mouse control.  If you need it docked 
in order to make a boot selection into android then undock it immediately after 
making the selection.

I am also having the display corruption issue, as well as no browser working on 
1225 Brazos (Acer laptop 5253-BZ661, Radeon HD 6310) WiFi and all other apps 
that use the Internet work beautifully 

The display corruption happens when coming out of hibernation, or when 
switching to another tty console and back using the Ctrl+Alt+ F1, etc keys

I'm very impressed with this otherwise, I'd like to run it full time on my 
laptop once this issue is fixed! =D battery life is PHENOMENAL with Android 
compared to a full OS. 

Will this likely be a fix I can do myself? Or will we have to reinstall? I'm 
trying to decide whether to tough it out or install an older version

Yes, I'm using a W500.  Can't get multi-touch in docked or undocked mode.  Not 
sure why.  Get the screen corruption that everyone else his having as well.  It 
happens after the screen blanker kicks in.

I'm also testing android-x86-4.0-amd_brazos-20120101.iso on my W500.  Seems 
much snappier than the previous version and thankfully the browser is working 
now.  Everything is working EXCEPT touch screen.  Also, I'm side booting ICS 
from the SD card.  Is anyone else booting from SD card and also missing touch?  
It seems like the folks booting from the internal hard drive aren't having this 
problem.  Comments?

I can confirm the same eventual pixel crash issue using 20120101 ICS 4.0 Brazos 
on an Acer Aspire 5253-BZ661. Everything else is amazing

It runs perfect!

screen crashe solved (great !)

Please try the new 4.0 Brazos build.  I have been up and running for 45 
minutes!  The last build was 20 minutes at best.  I still can not play video, 
but Android Sounds work.

Running this android-x86-4.0-amd_brazos-20120101.iso build from SD-card 
(installed from USBB) on my Acer Iconioa W500 makes it very workable (with the 
instruction of comment 6). The Windows 7 partition is not affected.
Some applications rotate the screen, without rotating it back after closure, 
but ticking the Camera icon rotates it back (without the camera working).
The screen timeout has to be set to 30 minutes, because when the system goes 
into standby, the screen is messed up and not able to recover. Is there a way 
to set the timeout to unlimited/off?
Sound works, wifi works, touch works.
The graphics are not ok, the screen flickers and the browser screen is often 
messed up, but moving the contents in the browser helps to redraw the contents.

All in all a very usable build, keep up the good work to create an even better 
one with all functionality!

I've a problem:

I have installed android-x86-4.0-amd_brazos-20120101.iso and when I first

Could you help me?

I'm done, running W500 with android-x86-4.0-amd_brazos-20120101, I installed it 
on SSD (create one new partion and format with Ex3), works great too... also 
more App not working, i thinks we make a list of App run or not run in 
Android-x86.

I also installed the 4.0 Brazos build on my iconia w500 from USB. Made the USB 
from lili USB creator. The weird thing was that it would only boot if I used my 
old 1gb thumb drive, it would lock up if I used a newer one. My old drive is 5 
or more years old, can't remember exactly.  I installed to the SSD and haven't 
had serious problems yet, just very few functional apps.

Youtube & other web-streaming videos used to work with 3.2 Brazos.  I wonder 
why the videos won't play with the ICS version.  Can there be a simple way to 
bring just the video functionality to the ICS?
