Hi,
I've tried googling various incantations of the problems we're having, and
what I think's causing them, but to no avail. So, I'm going to try the
list (note, I did try emailing David Miller and Jeff Garzik last week, but
haven't heard anything back). Can anyone offer guidance?
I'll summarize what our problems and config's are.
Problems - lockups on ethernet controllers under heavy NFS loads
(sometimes driver can/will reset, sometimes not)
systems completely lock up
Hardware - Supermicro H8SSL-i with onboard Broadcom 5704's (both clients
and servers)
Server config - 2.6.19 kernel (thus tg3 ver 3.69)
nfs-utils-1.0.7-13 FC4
NIC running at 4500 MTU
NIC exhibits lockup (NOT resettable?) with ASF enabled
NIC exhibits lockup (resettable?) with ASF disabled
Client config - 2.6.19 kernel
NIC running at 4500 MTU
autofs FC4 autofs-4.1.4-26
nfs-utils-1.0.7-13 FC4
using UDP for transport and -rsize=32768 -wsize=32768
Failure caused by users building software in automounted FS's.
Thanks in advance for ANY help!
Cheers,
Paul

Hi,
sorry for contacting you directly, and please let me know if you'd like me to
move this "discussion" to lkml (or somewhere else). I was wondering if either
of you could offer some guidance, or point me at someone who might be able to.
We have a large cluster of machines using integrated Broadcom 5704's that we're
having problems with. The original config reported as (BCM95704A6) rev 2100,
and after a firmware update to "fix" our problem, they report slightly
differently as (BCM95704) rev 2100.
Our problems involve the controllers locking up (recoverable if ASF disabled,
not if ASF enabled), especially under heavy NFS traffic. I've got more details
I can provide, but don't want to suck up any more bandwidth here than
necessary.
Can I bother you for some help?
Thanks!
Paul Armor
