I think so, Dave just checked the IRQ rates in systat and found
clk0: 153-157 (over a minute or so)
rtc0: 64 very steady
And this is wrong, they should hold a ratio of 100:128, and this is
clearly not the case (SMP shows 50:64 for some reason, UP 100:128).
I will probably have to hand this over to the real SMP wizards, (I've
CC'ed smp), because this looks like something related to the APIC/
MPTABLE and all that junk.
Dave, is ther by any chance a newer BIOS you could flash into the MB ?
SMP wizards, any good ideas ? hardclock gets called about three times too
often on this motherboard. Mptable & dmesg included:
