Hi Julien

It's the family HTPC/television system. The crash occurs approximately once per hour.

It occurs when there is a major screen change, e.g. on transition from the show to an advert or while jumping forward.
This problem started after upgrading nvidia 302.17-3. I suspect the kernel became RT at the same time.

Crash scenarios:
 - 80% of crashes the PC reboots, BIOS POST, etc.
 - 20% of crashes, the screen freezes and the PC loops the last 100ms or so of audio. When this occurs the PC is non-responsive. I have to reset it.

After the PC has rebooted (warm boot):
 - 70% of reboots, it crashes looping: "udevd[81]: timeout: killing '/sbin/modprobe"... as I'd described in message #10. The method I'd found to recover is to reboot again, select an earlier kernel at grub, let it fail because module nvidia is not found, then Alt-F1 to tty1 and reboot again.
 - 30% of reboots, it boots clean.

If the kernel crashes on boot, it will crash on every boot until it's booted to the earlier kernel.
My newest kernel is 3.2.0-3-rt-amd64.
My earlier kernel is 3.2.0-3-amd64.

Power-on (cold boot ) crashes about the same % as warm boots.

The attached dmesg was collected after booting to the earlier kernel, then booting back to the newer kernel.

Thanks
Alister
