ACPI problem report for Thinkpad X31
Hello,
after patiently waiting for the 2.6.2 kernel I just tested whether S3 suspend got better with 2.6.2. Unfortunately it did not. What I did:
echo 3 > /proc/acpi/sleep (without X, radeonfb)
System goes into suspend, moon LED is on but LCD backlight stays on. (actually, my thinkpad is attached to a port replicator with external monitor attached. So actually, on suspending the backlight switched on instead of keeping off)
On resume, backlight switches off again and the external monitor on, moon LED stays on and the whole thing hangs. Guessed that it was USB still hanging the system on resume (guessed right).
Tried again without USB drivers loaded. Suspend works as above. Resume now works, but prints two times:
MCE: The hardware reports a non fatal, correctable incident occured on CPU 0
Bank 1: f200000000000185
However, if I now try to reload ehci_hcd, it oopses - trying to reload uhci_hcd hangs the whole system. Hmmm. Bad.
At this stage, I didn't tried to go to S4.
Can you give me any hint whether you are knowing about these problems, know a fix or a mid-term solution for this? I really like my X31 and it would be really great if I could use S3 and S4 with it. (The whole speed step thingie with the Pentium M already works great, thank you).
Best regards,
Daniel
P.S. Please CC me on reply.

FIRST try S4. If this works, try S1 (if supported), if this works go on and fail on S3.
This is my experience with a lot (~10 different) machines. Even if a machine recovered from S3, there was always something not working 100%, or it was dieing sooner or later.
