Hi
Our nfs server recently paniced under heavy nfs load. The backtrace
indicates that this might be a problem with the tigon3 network driver
which drives the onboard chips of the machine.
The first crash under 2.6.21.1 happened after about 4 days of uptime,
2.6.21.5 already crashed after 15 Minutes.
Screenshots of the resulting kernel panics are available at
http://www.systemlinux.org/~maan/shots/huangho-crash-2.6.21.1.png
and
http://www.systemlinux.org/~maan/shots/huangho-crash-2.6.21.5.png
We're now running 2.6.18.6 again which happens to be rock solid for our
workload. However, this kernel now spits out zillons of messages like
[55122.674290] RPC: bad TCP reclen 0x00010094 (large)
I'm sure it didn't do that half a year ago when it was running for
several months. The 2.6.21.x kernels did not print these messages
either, but from what I understand this is due to a patch which went
in somewhere between 2.6.18 and 2.6.21 and which just ratelimited
the message.
So something weird seems to be going on in our network and this might
well be related to the 2.6.21.x crashes we are seeing.
Thanks
Andre

Looks the the known oops in show_mem(); patch is queued for 2.6.21.6.
But it is hard to tell when the screen shot doesn't show the whole
message...

I see. Thanks.

There's no way to scroll up after a kernel panic. I already changed
the video setting to use a smaller font, so if it happens again,
there will be more info visible.
