Comment 30 for bug 494476

This is a very serious problem. It's causing unpredictable lockups on my server every 2-3 days, requiring a force-reboot. There are many related reports from other users: e.g. #588046, #667656, #628530, and my particular one, #684654.

This bug is not:

* Just on server kernels. My kernel is the latest -generic.
* File-system specific. Here it's on ext4, mine is on reiserfs, others have reported it on xfs.
* A hardware problem, comment #29 notwithstanding. My hardware shows no signs of failure, and too many people are reporting it for it to be caused by simultaneous hardware problems.

I hope that someone is going to work on and fix this very soon.
Andrew.
