I'm currently running Linux Mint 10 (Ubuntu 10.10) on my Thinkpad W500 and have encountered an annoying issue... essentially I get an intermittent hang when I attempt to restart or logout.

This problem has been made more visible as of late possibly due to my screwing around with the hybrid switcheroo configurations (see: http://asusm51ta-with-linux.blogspot.com/ if you dare) but I don't know if this is the root cause... at least I don't recall directly if this problem started only when I made the changes detailed in the switcheroo procedure.

What is odd is that when I attempt to reboot via an application (in this case the UNetBootin utility) everything seems to work fine, however, attempting to do the same via the main desktop "Menu" usually causes a hang.

Although I've done my best with the details I know the description above is still vague, however, being relatively new to Linux (at least for anything beyond a regular user) I'm not sure where to start in terms of troubleshooting...

Executing dmesg (and grep'ing for "error") gives me the following:

[ 2.321362] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 1sec aborting
[ 2.321367] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing F6D8 (len 487, WS 0, PS 4) @ 0xF719
[ 3.361344] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 1sec aborting
[ 3.361348] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing F6D8 (len 487, WS 0, PS 4) @ 0xF719

(from the output of dmesg executed after a hard restart)

Additionally it seems that I am unable to "wake" my laptop once it suspends or goes to sleep.

Any ideas?

I have the same problem with my T60... did you find a workaround yet?

Please provide more specific information:

I saw this bug report the other day (in regards to suspend problem on ThinkPads). Don't know if the solution(s) have any relevance to your problem or not.

I had hang problems on boot-up and shutdown on my 3000 n100 with Ubuntu.
Sometimes it wouldn't happen but more often than not it would occur several times in a row before it would NOT occur.
After various Ubuntu updates, it occurred less and less. It hasn't happened again in, oh, a few weeks now.

I don't know if this will help, but Linux Mint 10 has been flawless with regard to suspend and resume on my X200s. I'm using this kernel (output of 'uname -a'):



It's working so well, I've decided to not do any more updates, especially of the kernel.

I tend not to shutdown or logout, preferring to suspend instead, but the few times I've done those operations I didn't see any hangs.

It would be interesting to know which kernels have been in use on the hanging machines.
