lspci output, from working 2.6.31

Upgrading to kernel 2.6.32.9 on a 64-bit machine (Fedora 12,
2.6.32.9-67.fc12.x86_64) caused breakage in transfer of large files over SSH
and SMB, followed by breaking network access.

To reproduce, copy a large file (> 900 MB) using SSH or SMB (mounted either
directly via "mount" or indirectly via "gfvs / nautilus").  Copy stalls and
network becomes unusable (e.g. can't ssh to any other host).

Previous kernel 2.6.31.12 (Fedora 12, 2.6.31.12-174.2.22.fc12.x86_64) works
fine.
