SubjectBUG: soft lockup detected on CPU#0! in sys_close and ext3
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:

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.
