Description Edmond Hui 2007-03-18 14:55:48 UTC
Description of problem: Kernel panic when running mencoder. I encountered a few similar cases, mostly related to heavy disk access with DVD burning, MySQL. The server is also running web server, mail server, bittorrent. Version-Release number of selected component (if applicable): kernel 2.6.20-1.2925.fc6 hw setup: MSI RS480M2-IL m/b (see http://www.msicomputer.com/product/p_spec.asp?model=RS480M2-IL&class=mb), AMD X2 3800+, 2 SATA HDD running hardward RAID from m/b, 2 ATA-100 This problem been happening since 2.6.19, 2.6.18 also have some disk related problem (DVD burning failed/crash), but disk access is stabled How reproducible: quite often 6/10 times Steps to Reproduce: run mencoder to convert mpeg video (capture by WinTV250 TV capture card) to avi. mencoder filename -ovc frameno -o frameno.avi -oac mp3lame -lameopts vbr=3 mencoder filename -ovc lavc -lavcopts vcodec=mpeg4:vpass=1 -oac copy -o filename.avi mencoder filename -ovc lavc -lavcopts vcodec=mpeg4:vpass=2 -oac copy -o filename.avi When burning DVD, I am using k3b, the hangs happened when verifying DVD burned. Actual results: kenerl panic, see attach screenshot Expected results: no error should encounter Additional info: I run smolt to collect my system setup, hw-uuid 72b5ecb7-7d79-4221-a16f-9e87491d3787

Comment 2 Chuck Ebbert 2007-03-18 22:30:38 UTC
Please try to boot in 50-line mode and capture the entire oops.
Comment 3 Edmond Hui 2007-03-18 22:39:44 UTC
how to do that? Rgds,
Comment 4 Dave Jones 2007-03-18 23:14:45 UTC
add vga=1 to your boot command line.
Comment 5 Edmond Hui 2007-03-18 23:41:46 UTC
I added it to /etc/grub.conf but it didn't work for me... I think my LCD display didn't support 50-line text mode
Comment 6 Chuck Ebbert 2007-03-19 15:26:19 UTC
Everything supports 50-line boot mode. Sometimes the default font causes problems, though. You can just rename the directory /lib/kbd/consolefonts to /lib/kbd/consolefonts.save ... just be sure to put it back after you are done. There will be annoying messages about "not able to find default font" but they are harmless. Or you could try "vga=792" for really small fonts...
Comment 7 Edmond Hui 2007-03-19 15:29:27 UTC
It's very unstable, I rollback default kernel back to 2.6.18 now. But I wil try to reproduce it tonight. Thanks for the response. Rgds,

Comment 10 Edmond Hui 2007-03-20 13:52:46 UTC
BTW, should point out that even under 2.6.18. Sometime the kernel reboot (after panic??) under heavy disk load... but 2.6.19/20 makes it worst that he panic frezzed.....

(This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora!
Comment 13 Edmond Hui 2008-01-08 02:59:18 UTC
Hi, I have not reproduce it in FC8, so please close this.
