Hi there,
Quick summry of this email
X server locks on thaw after hibernation with 340.32 and 340.24 drives
but does not with 319.32 drives.
The symptom is a black screen - unresponsive to virtual terminal keys
etc. The X server is chewing 100% CPU
distribution kubuntu 12.04
kernel 3.2.45
nvidia-drivers - 319.32 good - 340.24 and 340.32 bad
platforms - various - Dell’s and HP’s
nvidia cards 780’s and Quadro 5000’s
I’ll attach (when I find the attach function!) two nvidia bug report log files - one before I attempt a
hibernate and one after the thaw when Xorg is eating 100% of the CPU.
Long story
We are doing a lot of hibernation and thawing (40 machines a night at
the moment) and have found the 340.32 (and 24) drivers almost always
hang on thaw. Even if there are no users logged in and kdm is the only
thing running on the X server.
On the same hardware and OS the 319.32 driver works perfectly.
I’ve seen the problem on Dell and HP workstations.
A user doesn’t even have to be logged in for it to happen.
When the machine thaws the screen is black and Xorg is eating 100% CPU.
If I attach gdb to X and dump the stack I get:

The 343 drivers won’t start up. I’ll make a separate report for that.
