Was it just booting the kernel or were you adding or removing a module? Hi, sorry for the late respond. The messages are printed at booting time only. I just hit this bug about half an hour ago as well; similar stack trace (can post if necessary), same warning and offsets. Happened during ~10 seconds into boot without me doing anything to trigger it. After a little digging through my LKML archives I found a note from Thomas Gleixner: Subject: [BUG 2.6.36-rc6] list corruption in module_bug_finalize Message-ID: <alpine.LFD.2.00.1010032141410.14550> that seems related. There's a patch at the end of the thread. I'd try and find the a link to the post on lkml.org, but I'm having difficulty reaching that site. With any luck this small nugget will be of some help... Same here with kernel kernel-2.6.35.12-88.fc14.x86_64 *** Bug 651528 has been marked as a duplicate of this bug. *** *** Bug 693085 has been marked as a duplicate of this bug. *** *** Bug 737345 has been marked as a duplicate of this bug. *** I've added a backport of the commit highlighted in comment #7. Since this issue is intermittent, it's somewhat hard to say if the issue is fully resolved but the kernel seems to fare well in my local testing. The next F14 kernel build should have this included. that build is now out. This issue should be fixed. |
