Subject: Repeated XFS corruption -Corruption of in-memory data detected

Kernel: 2.6.18-4-amd64 (Debian 2.6.18.dfsg.1-12etch2) Debian Etch
System: Dell PowerEdge 1850
Processor: 3.2 GHz Intel Xeon w/ microcode v1.14a, Hyperthreading disabled.
RAM: 2x1GB ECC DDR-400
RAID Controller: Dell PERC5/E using megaraid driver

I got another unexpected error on my XFS partition today. I was able
to reboot the system normally and the journal recovered on the
following mount. Shortly thereafter, the error occurred again. After
this the filesystem was no longer able to be mounted as the error
would occur immediately.

The volume is on a 9.5TB LVM2 volume on a Dell MD1000 loaded with 15
750GB drives in a RAID5 set. Writeback is disabled. Memtest86+ was run
on this system for 48 hours without fault. The system is otherwise
stable.

XFS was able to repair the damage, but previously the drive returned
to its corrupted state within a few hours of heavy I/O.

Here is the message:
SGI XFS with ACLs, security attributes, realtime, large block/inode
numbers, no debug enabled
 SGI XFS Quota Management subsystem
 Filesystem "dm-3": Disabling barriers, not supported by the underlying device
 XFS mounting filesystem dm-3
