Aug 25 08:27:46 boar Kernel panic - not syncing: Fatal exception in interrupt
All you need is to put the oops into a file and then send this file as part of your problem report to
the Parallels support team.
Finding Kernel Function That Caused D Process State
If there are too many processes in the D state and you can't find out what is happening, issue the
following command:
# objdump -Dr /boot/vmlinux-`uname -r` >/tmp/kernel.dump
and then get the process list:
# ps axfwln
F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND
100 0 20418 20417 17 0 2588 684 - R ? 0:00 ps axfwln
100 0 1 0 8 0 1388 524 145186 S ? 0:00 init
040 0 8670 1 9 0 1448 960 145186 S ? 0:00 syslogd -m 0
040 0 8713 1 10 0 1616 1140 11ea02 S ? 0:00 crond
Look for a number under the WCHAN column for the process in question. Then, open
/tmp/kernel.dump in an editor, find that number in the first column and then scroll
backward to the first function name, which can look like this:
"c011e910 <sys_nanosleep>:"
Then you can tell if the process “lives” or is blocked into the found function.
