| |
Dear ext3 kernel maintainers,
I got two soft lockups on one of the CPUs just now. I'm unsure if this problem is in ext3, sys_close, or general kernel, so I've CC'd the kernel list.
[1.] One line summary of the problem:
BUG: soft lockup detected on CPU#0! in sys_close/fput and ext3 journaling
[2.] Full description of the problem/report:
First lockup was in syscall sys_close fput, second was in ext3 journal code.
No problems were noticed after the first lockup, except slower responsiveness. There was a number of hours between the two lockups.
The second lockup occured during or shortly after unauthoring a dvd, which was mounted via a loop device.
Only the mouse was moving after the second lockup. Sysrq wsa working, I could remotely log in and sync my disks, regular shutdown didn't work so I had to use sysrq umount, boot.
[3.] Keywords (i.e., modules, networking, kernel):
ext3 journal soft lockup sys_close fput
[4.] Kernel version (from /proc/version):
Linux version 2.6.18 (dennis@jumbo) (gcc version 3.4.6) #3 SMP Sun Oct 8 22:02:52 CEST 2006
[5.] Most recent kernel version which did not have the bug:
Haven't seen it in 2.6.15.1, didn't try anything in between.
[6.] Output of Oops.. message (if applicable) with symbolic information resolved (see Documentation/oops-tracing.txt)
Here is the bugtrace from dmesg:

There were a number of media errors on the dvd 1 day before the BUG occured.

I also reported a possibly related problem with "possible circular locking dependency detected" on the kernel mailing list (linux-kernel@vger.kernel.org). This didn't occur between the last reboot and the soft lockup bugs reported here.
