Public bug reported:
After issuing a suspend to RAM operation using pm-suspend the system
sporadically hangs while initiating the suspend with the following symptoms:
- HDDs are already spun down
- Fans are still running
- The power LED is constantly illuminated (instead of the typical blinking
sequence in S3)
- MagicSysRq is no longer working
This bug is a regression from Maverick (Kernel 2.6.35) where suspend to
RAM was working reliably. The issue can also be reproduced with a
vanilla 2.6.38 kernel (even with a 2.6.36 kernel). Attempts to bisect
the root cause have failed so far because of the sporadic nature of the
issue.
