Here is what I get when I reboot from FreeBSD-6.1-PRERELEASE after
installing new CURRENT kernel:
mpt0: Unhandled Event Notify Frame. Event 0x30.
mpt1: Unhandled Event Notify Frame. Event 0x30.

Interrupt storm detected on "irq9:"; throttling interrupt source
Rebooting...
cpu_reset: Stopping other CPUs
Here is cpu and cpu_class variables after booting to CURRENT:
GDB: no debug ports present
KDB: debugger backends: ddb
