Hi,

I just updated to the latest kernel in the updates of Fedora 11 and the
system is no longer using the 2 quad-core chips
The system is no longer seen as an SMP system using
kernel-2.6.30.9-96.fc11.x86_64

On the same system the older kernel works fine:
2.6.27.21-78.2.41.fc9.x86_64

On identical hardware but different server also running Fedora 11;
this kernel works fine:  2.6.30.9-90.fc11.x86_64


Is  this broken?:  2.6.30.9-96.fc11.x86_64


Thank you,
Kevin
