Yeah, processes should not get stuck in the D state like that.
1. Is this still reproducible? How do the latest squeeze and
sid kernels behave? (To test a sid kernel on a squeeze system,
the only packages aside from linux-image-foo you should need from
outside squeeze are linux-base and initramfs-tools.)
2. Please try uninstalling or blacklisting the nvidia driver to
make sure that is not the cause, and send full "dmesg" output
from this happening if possible.
3. Output from dmesg after running "echo t >/proc/sysrq-trigger"
while in this state would also be useful. (Or run
"echo 1 >/proc/sys/kernel/sysrq" to disable the paranoid checks
and press alt-sysrq + t while in that state. See
Documentation/sysrq.txt for details.)
4. (I'm just curious
Does the nouveau driver behave any
Thanks for reporting, and sorry for the slow response.
