Hi, when using kernel 3.4 I'm facing this error with nouveau :
[drm] nouveau 0000:01:00.0: Checking ACPI for VBIOS
ACPI Error: Field [ROMI] Base+Offset+Width 0+24+1 is beyond end of region [VROM] (length 24) (20120320/exfldio-210)
ACPI Error: Method parse/execution failed [\_SB_.PCI0.RP00.VGA_._ROM] (Node ffff880131dee050), AE_AML_REGION_LIMIT (20120320/psparse-536)
failed to evaluate ROM got AE_AML_REGION_LIMIT
And after that nouveau can't load. Is there something to do ?
Can you link to your acpidump on the LP bugreporter?
Here it is: https://bugs.launchpad.net/lpbugreporter/+bug/752542/comments/110 (old, but still accurate)
You're affected by https://bugzilla.kernel.org/show_bug.cgi?id=43063. What kernel still works for you? (e.g. 3.3.7?) Try booting some rc kernels in the range 3.4-rc0 to 3.4-rc7 (start with rc3, if it fails try rc1, if it succeeds, try rc5, etc). In order to speed up compilation time, use a minimal config. For example, I have disabled lots of modules and can compile a kernel in 6 minutes using 3 i5 machines with distcc.
I'm having three kernel on my laptop currently : 3.2, 3.4rc7, 3.4.
It works under 3.2, it has never worked under 3.4 (I also used 3.4rc6 and rc5 before).
I'm going to try some other RC and tell you the results.
In that case, start with 3.3. If that fails, try an older version, if it succeeds, try a newer version.
I'm having an issue, can't run any command in a term or tty (it just waits) with all kernel tried (from 3.3.7 to 3.4rc6), will try again today after changing some things.
By the way I would probably not be able to try 3.4rc1 and rc4 because of kernel panics on boot, one because of wifi probably, the other seems to be intel video driver.
Since you want to test nouveau, try to disable as much modules as possible. If you have a reliable ethernet driver (I have jme), use that if possible and drop wireless as that's more complex.
Fixed in kernel 3.5
