USB Boot hangs if second mass storage USB device attached #2377

Open swhobbit opened 6 years ago

swhobbit commented 6 years ago

System is Raspberry Pi 3, running stretch with recent patches applied.

Problem:

While system normally boots fine from SSD if no other mass storage is attached, if additional an empty USB device such a thumb drive is attached the boot hangs.

To Reproduce:

Expected Behavior:

Second non-bootable thumb drive does not affect boot. System boots successfully.

@ghollingworth Any comment @swhobbit Is this issue still present on the latest releases? There have been changes to the bootcode recently.

ghollingworth commented 6 years ago

On my list of things...

Still dies,  Says something like cannot mount from unknown device.  I can get a console panic (I have a lovely serial to USB adapter from the last time I was getting panics at boot), but not today.  I'm off to rescue a machine which is literally a museum piece ...

swhobbit commented 6 years ago

Ok. I retested. Thumbs down.

Brand new Raspberry Pi 3B+, connected to a SanDisk SD8SNAT128G1122 [128 GB] SSD. Software image is 2018-04-18-raspbian-stretch-lite.zip

That was installed on an SD Card and then transferred to the SSD. The 3B+ and drive boot fine together. I've been running the hardware twin to the drive off a older Raspbberry Pi 3 for months.

Both old and new boots & runs fine. That is, unless I put a Samsung 32G USB Thumbdrive (straight out of the packaging with two Samsung files still on it) in a slot and boot. Then I don't even get a rainbow screen.

Anything else I can provide?

Can you put in a bootcode.bin from:

https://github.com/raspberrypi/firmware/raw/master/boot/bootcode.bin

Onto an SD card with nothing else on the card, then do:

sed -i -e "s/BOOT_UART=0/BOOT_UART=1/" bootcode.bin

Then attach a serial device to the Pi with 115200 baud

Should give us some information...

Yes, it may be the weekend before I get to it.

I assume you mean a serial console, and to reboot after I do this. (Fortunately, I do own a serial console adapter; I just gotta go look up the pins ...).

I suppose I need not point out that's running sed on a binary file; I haven't used a text editor on a binary file since 1980.  :-)

Correct - we are already sufficiently disgusted with ourselves.

ghollingworth commented 6 years ago

Me not so much. ;)

swhobbit commented 6 years ago

Sorry for the delay, I was doing CPR on an IBM 4361 mainframe.

@ghollingworth Well, sed on MacOS was pretty disgusted with the idea, and refused to do it. Can you blame it? :-)

I moved the sd card over to the target Raspberry PI 3+ and sed was more wanton.

I booted successfully with the card in, added a thumb drive, booted (it panicked). Not shown is successful boot with card after thumb drive removed. Monolithic session log is attached.

Contents of thumb drive (vfat) was only classic Mac cruft:
