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.
