Public bug reported:
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)
