OK, the thing finally crashed (jeez - I can't believe I'm actually saying this :-). Here is what I see on the screen (hand typed, sorry if there are errors - my vision is getting blurry from all the hex): ------------------------------------------------- [<c020f01e>] netif_receive_skb [kernel] 0x13e (0xc2f01d1c) [<c020f15d>] process_backlog [kernel] 0x6d (0xc2f01d3c) [<c020f26a>] net_rx_action [kernel] 0x6a (0xc2f01d54) [<c0121e45>] do_softirq [kernel] 0x95 (0xc2f01d70) [<c02173e5>] .txt.lock.netfilter [kernel] 0xb6 (0xc2f01d88) [<c02297c0>] ip_queue_xmit2 [kernel] 0x0 (0xc2f01db0) [<c02284b3>] ip_queue_xmit [kernel] 0x483 (0xc2f01dc8) [<c02297c0>] ip_queue_xmit2 [kernel] 0x0 (0xc2f01de0) [<c023df8a>] tcp_v4_send_check [kernel] 0x4a (0xc2f01dfc) [<c0238928>] tcp_transmit_skb [kernel] 0x3b8 (0xc2f01e1c) [<c0239604>] tcp_write_xmit [kernel] 0x184 (0xc2f01e1c) [<c022dfce>] tcp_sendmsg [kernel] 0x5de (0xc2f01e84) [<c01188a0>] recalc_task_prio [kernel] 0x90 (0xc2f01ea4) [<c024bb02>] inet_recvmsg [kernel] 0x52 (0xc2f01ee0) [<c024bb62>] inet_sendmsg [kernel] 0x42 (0xc2f01efc) [<c0206f9b>] sock_sendmsg [kernel] 0x6b (0xc2f01f10) [<c020722e>] sock_write [kernel] 0xae (0xc2f01f54) [<c0144103>] sys_write [kernel] 0xa3 (0xc2f01f94) [<c0109747>] system_call [kernel] 0x33 (0xc2f01fc0) Code: 0f 0b 62 00 03 0c 28 c0 e9 6c fd ff ff 8d 74 26 00 55 57 56 <0>Kernel panic: Aiee, killing interrupt handler! In interrupt handler - not syncing ------------------------------------------------- Hope this helps. Well, the panic message and register dump has scrolled off.. When it dies, is the keyboard still responsive? If so, enable sysrq key and capture thread and register dumps, then sync and reboot. The traces should show up in /var/log/messages. Or else use a serial console to the box. How long does it take to crash? Please run slabtop every so many seconds and save the output. OK, I'll try what you suggested. BTW, I had sysrq key support in and I tried to sync, but noting showed up in /var/log/messages. Not sure why. I'll be more careful next time I crash the box and I'll try to catch more info. As for the time needed to crash the box - that varies. Sometimes it'll go down after a few minutes or so, sometimes it needs half an hour. Sometimes it'll run through all the tests just fine. Thanks for the hints. 83815 ethernet. Switched to FC2. We'll see what 2.6 does with it. Not sure if the new problem is related this bug or not, but I'll put the info here anyway. It may be useful. The platform this time is FC2, kernel 2.6.5-1.358. I'm using Apache 2.0.49 (compiled from source) with libapreq2 (from current CVS) to upload some files through an HTML form (all to/from localhost - I'm not connected to the network at all). When I do what with a relatively big file (around 9.5 MB), on occasion the machine will hang. There is nothing on the screen or log files that would suggest the error type - everything just freezes. Not sure if this is some kind of hardware problem (I've bumped the BIOS up on this notebook to the latest available from HP) or if it is kernel related like before. Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
