[Virtual-pkg-base-maintainers] Bug#638316: base: Task blocked for more than 120 seconds

[Timo Juhani Lindfors]

Hi,

thanks for reporting a bug. If at all possible, please try to isolate
the problem by not using ocfs2 during debugging. If the bug still
occurs, it would be interesting to see

cat /proc/version
cat /proc/cpuinfo
lsmod
dmesg
ps axuf

from domU and

xm info
xm dump-core $DOMAIN $DOMAIN.dump
crash -s --no_panic -e emacs /usr/lib/debug/boot/vmlinux-2.6.32-5-amd64 $DOMAIN.dump

from dom0. The commands that you want to type to the "crash>" prompt include at least

sys
ps

and "bt $PID" where $PID is the process that is in the "D" state.

Please make sure that the version number of the kernel that runs inside
the domU matches exactly the linux-image-2.6.32-5-amd64-dbg package that
you use to get /usr/lib/debug/boot/vmlinux-2.6.32-5-amd64.

-Timo
