I've found a similar situation, have any fix came forth?

Funny you should bring it up now. When I posted back in January it was suggested that I verify my hardware/memory was OK and also try to reproduce the bug on 2.4.24. So, I ran burnBX/burnMMX for a couple days, turned up no problems, did memtest86 overnight, also no problems, and then I switched to 2.4.24.

I have seen this as well, no problem on 2.4 + md (raid5) + lvm2, about every night on 2.6.2

I ran 2.4.24 (plus dm-1.00.07 for lvm2) for about 25 days and had no
problems.  This seemed like reasonable evidence the problem doesn't
exist (or takes longer to show up) in 2.4.24.  So then I switched to
2.6.2 (that being the latest 2.6 kernel).  After about six days uptime
on 2.6.2, I started seeing the problem again.

Can anyone suggest what the next step is?

I believe it is another stacking problem, since there is no problem with using only one of md and lvm2, but i have no idea how to get more details on this. I also am an ext3 only user so i have no idea if other fs are affected.

Here are the latest entries from my syslog (this is 2.6.2).  As it
usually does, this occurred early in the morning while the locatedb
was being updated.
