[Bug 578138] [NEW] Thinkpad T400 (model 2765-TDG) fails to resume after second suspend

[Miguel Martinez]

Public bug reported:

This Thinkpad T400 no longer suspends and resumes reliably, while it did
on Intrepid and perhaps in Jaunty (but I can't remember when the
regression started).

In an almost fully updated T400 (newest BIOS, 3.16 as of  May 5th, 2010,
did not upgrade hdd firmware), the first suspend and resume will work
flawlessly. However, after the second suspend, the machine won't resume.
The HDD light will blink once and there seems to be activity for about
one second. Nevertheless, the sleep light will remain on and only a
forced power off will allow me to restart the computer.

The logs I attach via apport have been produced after a successful
suspend-resume cycle.

In an almost identical fashion to bug #532374, this bug is perfectly
reproducible. Since it was stated that Lenovo released an updated BIOS,
I had hopes that they would also release a fix for the T400, but it
seems it doesn't apply.

Finally, I wanted to append all this data to bug #336431, but it was
marked as expired 20 days ago. I'd also like to add that bug #503762
seems different, since grep does not return anything related to error or
failure from /var/log/pm-suspend*.
