installing new CURRENT kernel:

mpt0: Unhandled Event Notify Frame. Event 0x30.
mpt1: Unhandled Event Notify Frame. Event 0x30.
Shutting down ACPI
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
