Re: NFS Server Not Responding after hw change (svc: transport busy, not enqueued)

However, as the
onboard LAN is able to handle Samba / scp but fails with NFS, I'm curious
if this is an actual hardware problem or a driver issue?  Does anyone
know where the appropriate place for this problem would be?  Is there an
atl1c list?

Adding netdev-u79uwXL29TaiAVqoAR/hOOOyGI2DFzLe@public.gmane.org  Could you repeat any details about
the exact models of the network interfaces?

--b.

For those of you just joining us, I have some new hardware that handles 
ssh, scp, and samba all fine but NFS does not work.  Put back in the old 
NIC and all services are functional.

The onboard LAN (the bad one!) as seen from lspci -vvv:

I've filed a bug here:

Basically I see this in dmesg on the buggy onboad LAN:
