2.6.32.30 reproducible oops at startup in acpi_ex_read_data_from_field

Same here on an X31 -- crash looks identical, happens every time on 2.6.32-20, while 2.6.32-19 works fine. I just took a picture of the oops with an 80x50 console, so I got a bit more of it. Haven't looked at the kernel to figure out what changed yet.

Same here.

IBM Thinkpad R60 (LEnovo) Same problem overhere.

Booting a recent upstream kernel 2.6.34 worked.

T42 is affected as well. -19 works fine.

Looking at
http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-lucid.git;a=commitdiff;h=3f80f9e8e30f4759ad0e29d23856126edbfc7b41
which I believe is the only commit between -19 and -20 that actually touches ACPI, I see one thing that is a bit bogus. In the chunk below (launchpad may mangle the formatting but I hope not):

+ /* allow full data read from EC address space */
+ if (obj_desc->field.region_obj->region.space_id ==
+ ACPI_ADR_SPACE_EC) {
+ if (obj_desc->common_field.bit_length > 8)
+ obj_desc->common_field.access_bit_width =
+ ACPI_ROUND_UP(obj_desc->common_field.
+ bit_length, 8);
+ obj_desc->common_field.access_byte_width =
+ ACPI_DIV_8(obj_desc->common_field.
+ access_bit_width);
+ }

This is a nested if, and the two assignments of rounded things are indented as if they were supposed to both be consequences of the inner if. But the brace is placed after the first if, so the assignment of ACPI_DIV_8 to the access_byte_width will happen even if bit_length is not > 8.

I haven't tried building a kernel with that fixed, and I don't know how this would cause the problem but it does look suspicious.

Oh well, launchpad killed the indentation -- follow the link to gitweb that I posted and look at the first chunk of the patch to see what I mean.

As Jamie indicates, a valid workaround for now is to boot into the GRUB menu (by pressing SHIFT) then booting into a previous kernel version.

Same here on a Toshiba Satellite L-40. The last line on the screen is
"usb 6-2: configuration #1 chosen from 1 choice "
Then it wont move anymore so I have to press Ctrl-Alt-Del to restart the system and chose another Kernel.

2.6.32-19 works fine.

This is looking like fall out from an EC fix. Building some test kernels to confirm this diagnosis. For now the -19 kernel should be a good fallback and can be reached by holding SHIFT as the BIOS fades out and then selecting the -19 kernel from the boot menu.

I am not sure if this is the same bug, but it looks similar.

Asus M51SN laptop (x86_64).

When I boot into -20 from after rebooting from a working kernel (-19) it hangs on photo 1. If I then do a shutdown using the power button and boot into -20 again, I always get photo 2.

ASUS UL 30

Same here on an Asus X53S (F3Sa): crash looks identical, happens every time on 2.6.32-20, while 2.6.32-19 works fine.

This bug was fixed in the package linux - 2.6.32-20.30

2.6.32-20.30 fixed the issue here thx

I can report that 2.6.32-20.30 fixed the issue on my T43 Lucid test host.

Thanks. 2.6.32-20.30 now works on my MacBook 4.1. Thanks

The fix (2.6.32-20.30) works for me as well on my T400 and T500.

Affects my T61 too. Booting in an old kernel is no bother, but it would be good to get a new up up for release.
Cheers, B

Here's the link of the upstream bug: https://bugzilla.kernel.org/show_bug.cgi?id=15749

At comment #7 you can check the proposed fix, but it's still outside Linus' tree.

2.6.32-20.30 now works on my ThinkPad X60s, thanks!

Just another "works for me now". Asus Z35F. Thank you!

Works for me also on UL30VT and M70vm. Thanks

2.6.32-20.30 also works for me on my Lenovo T43.

2.6.32-20.30 also now works fine for me on my Asus K60.

asus f3j also affected

After the update 2.6.32-20 is working on Toshiba Satellite L-40. Thanks!

The proper patch to apply on top of the stable one that caused this bug just got mainline, and the hash is 2060c44576c79086ff24718878d7edaa7384a985.

2.6.31-19-generic (64bit) was the last working kernel image.

The following versions did not work on my 64bit system:
2.6.32-19-generic
2.6.32-20-generic
2.6.32-21-generic

Will now try 2.6.32-20.30 ...

Oh, damn, 2.6.32-20.30 I already tried. Did not work too.

So. 2.6.32-19-generic (2.6.31-19.56) is still the last working kernel image :-(

Are you sure it's (still) this ACPI bug that's causing your trouble?
It's been fixed for everyone else for almost a week now.

Booting with 'acpi=off' in my kernel line in grub was the only way I
could boot the bugged kernel, you might want to try that for testing,
though falling back to 2.6.32-19 is more sane for using lucid.
