In 6.1-RELEASE there were a number of em driver stability and performance
issues. We would regularly see packet loss at low to moderate load. A
number of patches were applied that completely fixed the problem for us.
We installed 6.2-RELEASE, but even though 6.2 is supposed to have a
stable em driver, we are noticing the same packet loss problem again. We
updated to STABLE, and we didn't see any packet drops in our first day of
testing, but today we are seeing packet drops again.
Has anyone else experienced this? Are there known problems with the STABLE
tyan s5372 motherboard (bios v1.05)
2 intel x5355 processors
adaptec aic7902 scsi daughter card
there are 4 em interfaces (2 on-board, 2 from an add-on card), but we
are currently only using em0
We have experienced the packet drop problem with a custom kernel and with
the RELEASE SMP kernel.
