[hardy] sometimes fails to suspend, lots of kernel messages in logs

Hi Jos,

Care to pull in the latest updates and if the issue still exists, per the kernel team's bug policy, can you please attach the following information. Please be sure to attach each file as a separate attachment.

* cat /proc/version_signature > version.log
* dmesg > dmesg.log
* sudo lspci -vvnn > lspci-vvnn.log

For more information regarding the kernel team bug policy, please refer to https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help and feedback.

Ok, I retried with latest updates, and the behaviour has changed. I freshly booted, and then did the 4 command as described, and attached above. Then I tried to suspend 3 times, every time it took *very* long to go to sleep, more than one minute. Eventually it flashes some text on the screen about CIFS, and then goes to sleep. Before it would flash said text, and then come back up in X. In the dmesg I could find the text, it is:

[ 27.635409] CIFS VFS: Error connecting to IPv4 socket. Aborting operation
[ 27.635476] CIFS VFS: cifs_mount failed w/return code = -101

This message is repeated every time I try to suspend the machine. Laptop was running on battery power, and no CIFS shares are mounted. The SMB daemon is running however, but I have not defined any shares.

After the second suspend, the machine would power on again, and go into X, and the password dialog came up, but I could not type anything, move the mouse or switch VT. I suspended the machine again, and the next time it came up fine.

Attached is a dmesg after 3 suspend/resume cycles.

I was wrong in the previous post, the SMB daemon is not running, in fact it is not even installed. Why is it blocking on some CIFS call?

Ok, the CIFS error put me on the right track. There was a CIFS mount defined in /etc/fstab, from the work network, that is not accessible from home. I forgot the noauto parameter. After I added the noauto mount option, I was able to suspend resume 6 times in a row without problem. Marking as invalid.
