2.6.33-2.6.34-rc5 suspend issues

2.6.33-2.6.34-rc5 suspend issues

[Nico Schottelius]

[-- Attachment #1.1: Type: text/plain, Size: 733 bytes --]

Good morning hackers,

running either 2.6.33, 2.6.34-rc4-00082-g250541f or
2.6.34-rc5-00142-g33eaf78, I get the following behaviour:

- suspend & resume works once
- second time system
  a) hangs within the suspend process (2.6.33)
  b) suspends, but comes up with the bios screen after resume
     and hangs there forever (2.6.34-*)

This happens on a Lenovo X200 and X201, xorg running with the intel
driver, i915 module loaded with modeset=1.

dot-config attached.

Cheers,

Nico

Just tested on latest linux-2.6, the
same happens on 2.6.34-rc5-00211-gb91ce4d.

Also with 2.6.32.12. I'm wondering if there's any kernel
that works with the X201. At least for the X200, there
have been some.

There's one bit that needs to be set to stay in the acpi mode, and
there's blacklist somewhere...?

Don't know if I should answer the question, but the problem also happens
on 2.6.34-rc6-00063-gbe1066b.

Now compiling v2.6.34-rc6-106-gd93ac51.

Nico

Success, success! With 2.6.34-rc7 I can resume at least two times!

I'll keep an eye on it and notify you if things continue to work / break again.

Congratulations. I have no idea what fixed it, but hopefully it will
keep working.
