The system was suspended 20 minutes into the 9.10 update download since the suspend setting was not deactivated during the distribution update(!).

I then resumed the system and download and continued with the upgrade. Now I have a somewhat broken system (xubuntu boot splash instead of the normal splash) and a high number of crash reports to submit.

Hi Akash,

The warning reported here typically indicates that it took longer for your system to resume from suspend than expected. I believe there is a 5 sec barrier which your system likely exceeded. Based on your dmesg output I see PM: resume devices took 5.164 seconds. A patch to prevent this warning has been applied via bug 464552. As a result I'm marking this as a duplicate to bug 464552. Please continue to track this issue at that report. Thanks!
