Hi, Troy !
I will test the kernel-largesmp-2.6.9-42.0.10.EL.x86_64 as soon as
possible, but unfortunatley my machine is not really my machines ...
One of our scientific-groups has got the ownership and it's still in
production too .... :-)
I've contaced them for testing this new kernel and still waiting
for an answer ...
I will report to you again if i've tested the kernel ..
Cheers & nice weeekend
