I also get a similar message on an ASUS CUR-DLS based PIII/1000 Mhz SMP
sometimes in UP, but very often in SMP mode. When calling
'systat -vmstat 1'
on the console or within a terminal window I get a weird essage: the
alternate system clock has
died. RTC seems to be all right. Using UP kernel hides away this problem
in most cases.
I use FreeBSD 5.3-STABLE. ACPI is enabled, but problem still remains
when ACPI has been disabled.
SMP is about to crash this system, UP is ok.
