I recently upgraded my old MSI based Pentium IV motherboard to new Asus M4A79XTD EVO/USB3 and AMD Phenom II X6 1090T with 4 Gb ram. I kept the old HD with Ubuntu 10.10 installed.

After the update I noticed that neither suspend or hibernate doesn't work. Screen goes blank, some lines are displayed and then it returns to login screen.

When checking dmesg I found these two lines which might be the reason for the failure:

[26138.433568] pm_op(): usb_dev_suspend+0x0/0x20 returns -2
[26138.433570] PM: Device usb8 failed to suspend: error -2

Here's the output of lsusb:

Any ideas how to get suspend work?

When I replaced my motherboard, Ubuntu had some weird quirks I was never able to resolve. I ended up reinstalling when a new distribution came out and it solved my issues. Perhaps you will need to the that same. –  Alex Nov 7 '10 at 20:14

Found the answer, USB3 causes problems and unloading the xhci module helps, more information here:
