Comment 2 Jeff Layton 2008-04-03 13:49:29 UTC 
This should already be fixed in the upcoming 4.7 update. If you have a
non-critical place to do so, then please test the kernels on my people page and
let me know whether they resolve the issue for you:

I just tested kernel-smp-2.6.9-68.27.EL.jtltest.34.i686.rpm from that page and
it works as expected. 

Thanks for the quick response.
Comment 4 Jeff Layton 2008-04-03 16:46:36 UTC 
Glad to hear it. It should be fixed in 4.7.
