If you are not tired, I'd suggest two more tests:
I volunteered to help :)
For the sake of testing up-to-date code, I performed the following
tests with 2.6.20-rc4.
First test was the usual nfs video playback. Crashdump is
panic-2.6.20-rc4-nfs.txt. Went down in about 20mn.
- as above but with NIC set to 100Mbps also,
Couldn't crash the machine (or at least it didn't happen in the time
frame I was willing to wait for doing ftp downloads, ~20mn). One note
though:
The throughput of the card was terribly sucky when set in 100-FD: I
couldn't get more than 5,5MB/s doing ftp get writing to /dev/null (to
rule out disk perf), ie, half the max link speed, though the /only/
thing I changed in the setup was the link speed (same switch - made
sure it properly detected link speed/duplex, same file server, same
everything else).
When configured in 1000-FD, still writing to /dev/null I could get
about 60MB/s. Again half link speed, but there, I suppose that the
remote fileserver couldn't pull data faster from the disks :)
- long downloading but without nfs e.g. ftp
That was fast and easy. In 1000-FD, I took down the box in 2s (after
downloading 90MB). Crashdump is panic-2.6.20-rc4-ftp.txt
(btw. there were some patches after 2.6.19
for rpc memory races).
It seems that's something else. I think I also reproduced the bug
while surfing the internet with firefox, but I didn't have serial line
hooked to capture a dump, unfortunately.
PS: Maintainers were cc-ed, I hope?
Now they are :)
