Description of problem:
Normally, if /proc/sys/kernel/panic is > 0, system reboots after disudmp finished. But on SMP machine, system doesn't reboot after diskdump (or netdump) finished.
When CPU#0 executed diskdump, system reboots. But When other CPU executed diskdump, system doesn't reboot.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Configure diskdump (or netdump).
2.echo 1 > /proc/sys/kernel/sysrq
3.echo 5 > /proc/sys/kernel/panic
4.echo c > /proc/sysrq-trigger
Diskdump completed, but system stopped at following:
CPU frozen: #0#1#3
CPU#2 is executing diskdump.
check dump partition...
<6>disk_dump: diskdump succeeded
<0>Rebooting in 5 seconds..
Actual Results: System doesn't reboot after diskdump finished.
Expected Results: If /proc/sys/kernel/panic is > 0, system reboot after diskdump finished.
Could you first check on whether Update1 kernel has the same problem as the
kernel that you used?
