oops in XFS

[Brasseur Valéry <Valery.Brasseur@xxxxxxxxxxxxxx>]

I am using 2.4.18 + XFS and got a Oops  last night.

the partition is on a Compaq Smart Array with on logical volume RAID 0
(striping 128K) using 3 disk.

mount options are :
/dev/ida/c0d1p1 on /mqueue type xfs
(rw,noatime,nodiratime,logbufs=8,logbsize=32768,osyncisdsync,kio)

this partion is for Postfix mailqueue.


here is the Oops trace :
