I think I found the block of code that hoses my CMOS with an SMP kernel.
Line 2260 of i386/i386/mp_machdep.c in start_ap() where the first
startup IPI is done.
/* do a STARTUP IPI */
lapic.icr_lo = icr_lo | 0x00000600 | vector;
while (lapic.icr_lo & APIC_DELSTAT_MASK)
/* spin */ ;
u_sleep(200); /* wait ~200uS */
Can someone else who has been experiencing CMOS damage verify this?
