Fwd: xfs_force_shutdown(md(9,0),0x8) called from line 1070 of file xfs_trans.c.

Hi all,

we're having nasty problems an our new raid on a linux box:
When performing hevy i/o (in present case was  scp -r),  the disks
get disconnected with this kernel message:

-----
Dec  3 15:55:34  machine sshd(pam_unix)[1791]: session opened for
user xxxx by (uid=500)
Dec  3 15:56:08 machine kernel: 0x0: 58 41 47 46 00 00 00 01 00 00 00

Dec  3 15:56:08 machine kernel: xfs_force_shutdown(md(9,0),0x8)
called from line 1070 of file xfs_trans.c.  Return address =

Dec  3 15:56:08 machine  kernel: Filesystem "md(9,0)": Corruption of
in-memory data detected.  Shutting down filesystem: md(9,0)
Dec  3 15:56:08 machine kernel: Please umount the filesystem, and
rectify the problem(s)
------

What is the nature of this problem? Kernel drivers?  Hardware
failure? Filesystem inconsistency?

What can be a possible solution?

Thanks so much,

alberto.

p.s. this  machine is not (_yet_) a Debian one. It came as a 
Mandrake, but this problem  may not be distro-dependent. Before 
upgrading to Debian I'd like to understand what is going on with my 
hardware.
