I had been running CentOS 5 happily on my Sun Fire X4200 M2 systems,
then I upgraded the BIOS and iLOM firmware. Now I'm running into what
seems to be a fairly common problem with newer motherboards. I cannot
boot unless I use the 'noapic' kernel option. If I try to boot the
kernel normally, I get the error:
"MP-BIOS bug: 8254 timer not connected to IO-APIC"
I can boot using noapic, but interrupts are *HORRIBLE* with noapic on
the X4200 M2. Here is a system with the new BIOS running with noapic:
What firmware version is it? I'm running on the version from the
FW12201_BIOS61600_4100M213.iso disk on Sun's web site and don't see that
error when booting.
