Moving out to RHEL 6.1, if QE can reproduce the problem for us then we can reopen the issue.

Comment 8 Prarit Bhargava 2010-08-10 18:29:50 UTC
I've looked at the code forwards, backward, and upside down, looking for a situation where the cpu_hotplug.lock is acquired after a cpu's cpu_policy_rwsem.

I can't find one :/.  This could be a symptom of the strange race described in the description of cpu_hotplug_begin() ... but it doesn't feel like that is the cause.

This has happened one time, and doesn't appear to be easily reproducible so I'm moving this to 6.1 for now.

Has this happened again?  I cannot find any bugs on suspend/resume on the x200 in bugzilla ...


Comment 12 Prarit Bhargava 2011-04-20 13:23:08 UTC
I had Cai's x200 here for a few days and used it diagnose another failure with suspend/resume.

I did not see the type of issue being reported in this BZ.
