[K12OSN] Re: Hard lockup

[James P. Kinney III]

I upgraded to the 2.6.18 kernel and the hard lock is no longer an issue.
Further, I was having problems with NFS exports being served reliably in
the earlier 2.6.17 kernels. the /proc listing for exportfs was blank
even after running exportfs -rva  many times. Again, the 2.6.18 kernel
has this issue resolved for the 64-bit dual core, dual socket Opteron
systems.

To sum up what I was seeing: 4 64-bit cores was not reliable on any of
the 2.6.17 kernels. So far, all is well on the 2.6.18 kernel with 4
64-bit cores.
