Hello all,

  I have a lovely server that I've been running a various stable -current
on for a few years now--it's a dell poweredge 600sc with the ServerWorks
SL chipset, intel gigabit onboard & a 3ware raid card.  It has served as
a fairly heavy-duty file server & various other not-too-taxing stuff.

  I've not had any problems with it, until we needed a lot more space &
got an Xserver RAID to attach--I've been running into lots of problems
with it.  I got an apple fibre channel PCI-X card (LSI 929X) which worked
beautifully with the Xserve RAID on another machine, with an Intel 850
chipset (I think). (and a 3com 10/100 card)

  When the xserve raid is in the 600sc there were several issues--first
off the non-ACPI kernel I had didn't work--it crashed when I was dumping
from the 3ware raid to the Xserve RAID..  Finally with an ACPI kernel
everything started to look good, but now about twice or four times a day
I get

wm0: Received overrun

and the machine stop responding to pings for a ~10 seconds--it can still
ping itself, but can't ping out.  it's light on the switch stays on.

  These might be related to lots of traffic coming through the ethernet,
but I'm not 100% sure about this..  (sometimes it seems to happen when
there is very little traffic goingon)

There are also some oddities with samba traffic that I haven't had before..

  I'm not sure what is going on...  any input is definitely welcomed--the
kernel is a patched version from Jason Thorpe to get the kernel to
recognise the full size of the raid array.  The kernel was really stable
in the machine w/ the Intel 850 chipset.
  Any better suggestions on really nice gigabit cards? I've always been
pretty happy with intel's "wm".. "gsip"s never really worked super well
for me.. 

Thank you for any input!
Jonathan
