Package: linux-image-2.6.18-6-amd64 Version: 2.6.18.dfsg.1-18etch1 Severity: critical Justification: breaks the whole system
Kernel using Linux dove 2.6.18-6-amd64 #1 SMP on debian etch. On high i/o load (using qpopper or dovecot services) we get random kernel stack traces,. We cannot reproduce this problem. After that the server is unstable and continues random kernel stacktraces. Sometimes it stalled an nfs mountpoint and the only solution is reboot to get it back. (if you try to mount - umount the nfs volume you get NO success - nfs is still stalled - this behaviour is only after kernel stacktrace. We get the same behaviour on 2.6.18-1 to 2.6.18-6 and ONLY on 64bit systems. 32bit systems are fine with no problems on high i/o throughput. I have attached some logs from messages.
