It appears there is an issue with the e1000 driver and this debian kernel.
I did not witness the system crashing, but if there is significant network
traffic
then the Ethernet device hangs for a while, sometimes seconds, until it
recovers
and a debug message starting with Detected Tx Unit Hang is printed to the
console.
I believe the problem is caused by having over 4 GB of memory and can be fixed
by
compiling the e1000 driver version 8.0.35 from source however I could not get it
to compile with Linux 3.2.x kernel and it looks like support has been ended for
that
driver and it is only now supported as part of the kernel.
With the source compiled version it lets you add an option ignore_64bit_dma=1
to the module which might fix the problem but I could not try it.
