no boot with kernel 2.6.31-2.fc12.i686.PAE

[José Matos]

Hi,
	my desktop machine that is running rawhide does not boot with the latest 
kernel (2.6.31-2.fc12.i686.PAE). I get the following error message when 
booting:

..MP-BIOS bug: 8254 timer not connected to IO-APIC
kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

The same system runs fine with 2.6.31-0.204.rc9.fc12.i686.PAE as it had with 
all the kernels tested until the final 2.6.31.

IS this known? Should I report this to bugzilla and if so what information is 
needed?

Regards,
