Bug Description
I am working on desktop machine with Nvidia Quadro FX4600 graphics card and two internal hard disks. Normally, resume after suspend will work.
But sometimes I can see the following error messages when waking up the system again:
ata2: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4
(I am not sure if this is really the text displayed on the console; but I found this text in the syslog and it says the same thing. the text on the console disappears very fast)
Then the system switches to a black screen with only the mouse pointer visible and completely locks up. I can move the mouse, but cannot do anything else. I have to hard power off the system then and reboot.
See the attached log files for details (The resume time was Nov 16 15:13)

This defect affect me too.
I have HP 6510b laptop with Kingston SSD as storage.
No problem in Karmic.
The error message from console differs a bit (not sure about the text), but it states something about "ATA I/O error at " and some number.
