SMP mptable bad signature

Hello list,

After updating to the most recent kernel (kernel-2.6.15-1.2054_FC5), I 
started getting a new error at startup.  At the point where I would 
normally see a whole bunch of stuff like messages from SELinux and udev 
whiz by, I only get one error message, that says something like "SMP 
mptable: bad signature (0x0)", followed by "BIOS bug: MP Table errors 
detected (see hw vendor)".  After that, the kernel starts to boot, and 
the Fedora interface begins loading.

I'm not sure if this error was always there, but until now I have never 
seen it.  It may be that I just never saw it because of all the 
SELinux/udev messages and such that normally scrolled by before (the 
older kernel that I have installed is kernel-2.6.15-1.2032_FC5, and it 
still shows these startup messages).  The machine seems to have booted 
fine, and despite not seeing any SELinux/udev messages at the initial 
startup, everything seems to be working the same as before.  Is there 
anything I should try in order to fix this SMP error, or can it safely 
be ignored?
