I've experienced same. I'll dble ck which kernel I'm running but I
noticed serious lock ups with various 'newer' smp kernels. I'll post the
one that has given me the least heartache. FC2 has been okay. FC3
nothing but problems though it was quite peppy even if it died rapidly
try different kernels would be my suggestion.
best of luck
