latest Oops
This is the ksymoops report for the latest Oops I generated.
(I'm not sure what the reason is for the "cannot stat" errors. If you can tell
me how to correct that, I'll re-generate the report.)
Ok, a little more information. The oops is related to triggering recovery processes. For example, the following command (which simulates a failure and replacement) frequently causes an oops: $ mdadm /dev/md0 -f /dev/sdc1 -r /dev/sdc1 -a /dev/sdc1 (I can cause oopses to occur with the raidtools commands as well.) I generated two more oops reports this afternoon; I'll attach them in a moment. Created attachment 89627 [details]

Uhhh... the previous oops report isn't a patch, obviously. Oops. :p
Ok, from pondering the 3 oops I've made so far, they're all clearly the same problem, so I won't bother to attach any more oops. (Unless I can get an oops in a different location, that is.) I've updated the summary of this bug to more accurately reflect the problem. I've skimmed through /usr/src/linux-2.4.18-19.8.0/drivers/md/md.c, but alas, I have little kernel hacking experience; whatever the bug, it isn't immediately apparent to me. I'm no stranger to building customized Red Hat kernels. If this oops is a known bug, and there's a patch, smack it in here and I'll go build my own kernel and test it. In the meantime, I'll compare md.c from 2.4.18-19.8.0 again Phoebe's kernel, and against vanilla 2.4.20. Perhaps something will leap out from the diffs... 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/ |
