[parisc-linux] killing a set of user processes causes system reboot

[John David Anglin]

After a GCC build and check, I sometimes see some sleeping processes
that didn't terminate:

dave at hiauly6:~/gnu/gcc-4.2/objdir$ ps -ef|grep dave
dave      2496     1  0 12:04 ?        00:00:00 /home/dave/gnu/gcc-4.2/objdir/hppa-linux/libjava/testsuite/Process_3.exe
dave      2497     1  0 12:04 ?        00:00:00 /home/dave/gnu/gcc-4.2/objdir/hppa-linux/libjava/testsuite/Process_3.exe
dave      2498     1 39 12:04 ?        01:59:20 /home/dave/gnu/gcc-4.2/objdir/hppa-linux/libjava/testsuite/Process_3.exe
dave      2873     1  0 12:09 ?        00:00:00 /home/dave/gnu/gcc-4.2/objdir/hppa-linux/libjava/testsuite/Process_3.exe
dave      2874     1  0 12:09 ?        00:00:00 /home/dave/gnu/gcc-4.2/objdir/hppa-linux/libjava/testsuite/Process_3.exe
dave      2875     1 39 12:09 ?        01:56:30 /home/dave/gnu/gcc-4.2/objdir/hppa-linux/libjava/testsuite/Process_3.exe

If I kill them, the system reboots with no messages as to why:

root at hiauly6:/home/dave/gnu/gcc-4.2/objdir# kill -9 2496 2497 2498 2873 2874 2875

I had strace attached to one of the processes but it gave no info:
root at hiauly6:/home/dave# strace -p 2875
Process 2875 attached - interrupt to quit

I've seen this with 32-bit c3k kernel versions 2.6.18-rc7-pa1
and 2.6.19-g211c7899-dirty.

Thoughts?

Dave
