Hi Ben,
I haven't been able to boot any 3.7 kernels since there's a regression which freezes my machine hard (a lenovo t530 with the dreaded optimus thing).
3.6 used to work but 3.7 get stuck at (copied by hand but I have an ugly screenshot if you'd like): nouveau [ VBIOS][0000:01:00.0] running init tables
Note my uefi settings weren't modified during the whole thing.
I've bisected the issue and git found that commit 4196fa is the one causing trouble (looking at the diff, it's pretty big):
Author: Ben Skeggs bskeggs@redhat.com Date: Tue Jul 10 14:36:38 2012 +1000
drm/nouveau/i2c: port to subdev interfaces
v2/v3: Ben Skeggs bskeggs@redhat.com - fix typo in default bus selection - fix accidental loss of destructor
v4: Dmitry Eremin-Solenikov dmitry_eremin@mentor.com - fix typo causing incorrect default i2c port settings when no BMP data
While bisecting the matter, I had a couple of messages like the following (6 actually). The addresses were always different (I could send another ugly screenshot if you'd like).
Condition still not met after 2000ms, skipping following opcodes
followed by:
Parsing VBIOUS init table 1 at offset 0x8183
At this point, the kernel was frozen hard (sysrq wasn't working)...
I'm attaching the output of lspci and my kernel config.
If you'd like me to add some debug statements or if you need more info, feel free, I'd love to help.
Cheers,
