I got similar messages some days ago on different hardware (see attached
file).
Both servers are
- running the same version of kernel and Debian
- inter-connected with two Ethernet cross-cables in bond
(balance-rr) with bridge and two vlans with MTU 9000 on top of it
- totally different on hardware
- server1 is Xeon 3210 based with all Intel Ethernet cards
- server2 is Opteron 2431 based with Broadcom Ethernet cards
