Richard,
Yes, I need the tx timeout lines. Those tell me if the patch was
successfull in solving the interrupt enablement issue. From your
statement below, it appears that it was either unsucessful (and you
didn't wait long enough for it to timeout) or the root problem lies
somewhere else.
Please give it a good 20 minutes (if you can get away with it being
down for that long) to timeout, as it has been taking 5-10 minutes in
your previous errors. There is no set timeframe for it to timeout.
It will only timeout after netif_stop_queue has true for a minute. if
this never happens, then it leads me to believe that the adapter is
still functioning. I know you can't log in to the system because of
the nfs mounts, but can you see if the system is pingable before you
reboot it?
Hi Jon!
No, the system is not pingable from the outside but it still responds to
pings from the inside after the hang happens if i'm logged in.
Here the last hang data. I can't get it to print the "tx timeout" lines.
Two hangs today, I waited 35/40 min and still no "tx timeout". But I got
"Transmit error, TxStatus ..." lines which were not there in the past
hangs. I must admit that I did a SuSE kernel update.
I had 2.6.8-24.5 installed now I have 2.6.8-24.10.
The dl2k driver is the same on both versions, your patch applied
cleanly, the hang is still there.
How can I get "netif_stop_queue to have true for a minute" as you
described to get the "tx timed out" lines? I can login before the hang
and stay logged in to give some commands or get any more data that you
could use to continue searching ...
Thanks, Richard
