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.
