Hello All. Please help cassify bug to report to bugzilla it!

Look to my sysctl:

# sysctl -a | grep panic
kernel.panic = 3
kernel.panic_on_oops = 1
kernel.unknown_nmi_panic = 1
kernel.panic_on_unrecovered_nmi = 1
vm.panic_on_oom = 0
# sysctl -a | grep nmi
kernel.unknown_nmi_panic = 1
kernel.nmi_watchdog = 1
kernel.panic_on_unrecovered_nmi = 1

# sysctl -a | grep rq
kernel.sysrq = 1

But computer do not reboot and ALT+SysRQ+B don't work...

This i get by netconsole and on the screen:
