Unable to load nvme kernel module after applying the fix #1

Closed lemourin closed 8 years ago

Hi, after applying the fix, my system says there is no root partition(in my case /dev/nvme0n1p6) and then it shows me the (initramfs): prompt. I'm using Ubuntu 16.10 with the systemd-boot bootloader; I also tried the fix on Arch Linux, but with the same result. I uploaded dmesg log from that failed startup, there are some lines I find interesting: [ 0.235414] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM [ 2.715192] nvme nvme0: Removing after probe failure status: -19 I was able to retrieve this log by plugging in a simple pendrive, /dev/sdX partitions seem to work.

Edit: I tried to use ssdt5_orig.dsl as the ssdt5.dsl file, I just changed DefinitionBlock ("", "SSDT", 2, "SaSsdt", "SaSsdt ", 0x00003000) to DefinitionBlock ("", "SSDT", 2, "SaSsdt", "SaSsdt ", 0x00003001) and the issue still persists D: So the conclusion is that our ssdt5_orig.dsl files should be different.

Hmm. Ok let's compare our original SSDT tables. I added a simple script to extract and disassemble the ACPI tables. This will create a compressed archive. Please upload it. The generated SSDTs tabled will differ from the previous acpidumps...

EDIT:

The following can be ignored. This is just a warning and I get the same message.

[ 0.235414] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM

-19 in the other error is a Linux System error of type: No such device. I have to see the diffs of the SSDTs...

EDIT: I got it working ;D I found the diff between your ssdt5_orig.dsl and my ssdt5.dsl. It was: 73c73 < OperationRegion (SANV, SystemMemory, 0x3AE16D98, 0x013F) --- > OperationRegion (SANV, SystemMemory, 0x3AE5ED98, 0x013F)

I fixed it accordingly in repository's ssdt5.dsl and now it works like a charm ;D Now I have working touchpad AND bbswitch. Thanks!

Great! I changed the build process to use the ACPI tables of the local build machine. 00a5709e2a930a95c5ba23c65719208588ee3a61

Can you give it a try if this works now for you?

sudo make all
sudo make install

Looks like your new scripts are working ;D I guess the issue can be closed now.

Perfect!
