I believe that it is related to the network, because sometimes I can actually log in (gnomes session) and as soon as I do some network related suddenly hard hang, not even Sysrq working anymore. Interestingly it only happens at a specific AP where the ESSID is hidden (at work). At home I can work without any problems (ESSID not hidden). Unfortunately I cannot set up a serial console or similar. Is there still anything else I can provide you for tracking that down.

I tried it today, but had "real work" (university job) to do. It worked and I found out that it happend (up to now) *NOT* when I was only doing a ping on a server, but when I ssh-ed into my server it hang. More testing tomorrow (here it is already 2am). BTW, logs were empty, unfortunately, complete hard hang. > > Jan 17 03:28:58 mithrandir kernel: [34535.332419] iwlagn 0000:06:00.0: BUG_ON idx doesn't match seq control idx=170, seq_idx=3466, seq=55456 > > > > Actually many many many of these lines. > > > > What you are seeing here is currently being looked into at > http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2098 - could you > please add your information there?

Ok, I can confirm that setting up the network is not the problem, nor is it pinging other hosts. But ssh-ing into another server made it go boom. From the screenshot I attach it looks like something in TCP code (that explains why it does not happen in pings), below I see tcp_data_snd_check I managed to swithc in time to a console with tail -f syslog before it hard locked up. The log files are empty, but I got a screenshot photo which has some hopefully useful information. I cannot scroll up or down anymore ...

The stacktrace would be a lot more useful with it set, yes. Other than that, I don't know. If there's a way to make your display resolution higher that might be useful so more info fits on the screen, or maybe trimming the stack trace depth (though I don't know if that's possible, I do know it is on powerpc because I added it there but not sure on x86) All assuming you can reproduce this issue, of course. johannes [-- Attachment #2: This is a digitally signed message part --] [-- Type: application/pgp-signature, Size: 801 bytes --] ^ permalink raw reply [flat|nested] 18+ messages in thread

I patched it into the kernel plus activated CONFIG_FRAME_POINTER which led to the same hang (not surprisingly, the patch does only debug more ;-) This time unfortunately I there was too much output to actually capture it. @Johannes: 100% reproducible. Everytime I boot into 33-rc4 and ssh into any remote place it goes boom. 100%. Maybe another tidbig might help: With 2.6.32.3 it happens that I have hickups with WLAN: [ 996.514491] iwlagn 0000:06:00.0: iwl_tx_agg_start on ra = 00:24:c4:ab:bb:42 tid = 0 and the connections needs 10-20secs (hard to guess) until it is back alive.

Thank you very much Done that, http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2155 Should that be a bug in the kernel bugzilla as regression, too? I mean 2.6.32.N does not suffer from that.

It is easier for our team to track bugs in our bugzilla. That is where we will be working on resolving this issue. If you would like to submit a kernel bugzilla for the purpose of tracking a regression you are welcome to, please then just use it for that purpose and point people to our bugzilla for the details and latest status of this issue.
