<oops - forgot to attach the back trace>

The following has been seen for some time on an intermittent basis. less
than 1:20 runs. Having trouble debugging it so I added some code to
panic.c:panic() to abort() and dump core. Also attached is a back trace
from that.

Kernel panic: handle_trap - failed to wait at end of syscall, errno = 2,
status = 383

appreciate any tips or tricks to get more information about this problem.

I have a core if that helps.

regards, Giovanni

ps. The kernel I am running is slightly modified but I do not believe
that is related. I will look more on a vanilla kernel just to be sure.
