Hi,
I've just found this thread, and i'm relieved in some way, that i'm not
the only one
experiencing this.
NFS Server: NetApp Data On Tap v 7.2.4 (not changed
NFS Client: Dell and HP machines, using Broadcom network card
# ethtool -i eth0
driver: bnx2
version: 1.7.4
firmware-version: 4.0.3 UMP 1.1.9
bus-info: 0000:05:00.0
All machines are running on NFS Root on local LAN. Previous
configuration with kernel 2.6.22.14
was working quite fine except for some quick lost, solved within a few
second
Sep 10 01:03:54 kernel: nfs: server 10.250.255.253 not responding,
still trying
Sep 10 01:03:54 kernel: nfs: server 10.250.255.253 OK
That's already something strange that shouldn't happens
And now, after an upgrade to 2.6.25.16:
Sep 10 03:26:31 web-31-mtp-1 kernel: nfs: server 10.250.255.253 not
