Hoping someone else has seen this before.
I have a few dozen Dell R610 systems with CentOS 5.2 that are using kernels from 5.3 and 5.4 (2.6.18-128.1.10.el5 & 2.6.18-164.6.1.el5), that at random lose layer 2 network connectivity either partially or totally. Running tcpdump on the interface reveals only ARP broadcasts, no responses. Switch reports no packets being received on the interface.
A colleague of mine has seen the exact same issue with Dell R610 systems running CentOS 5.x
It looks like this might be the same issue as:
https://bugzilla.redhat.com/show_bug.cgi?id=520888
Which seems to suggest disabling MSI - i.e. load the bnx2 module with "disable_msi=1"
We haven't tried this yet (as we went back to using CentOS 4 on these boxes - which works OK)
