Hello Debian Kernel list,

I'm experiencing a lot of soft lockups with the 2.6.24-etchnhalf kernel
and JFS on a Etch installation:

BUG: soft lockup - CPU#0 stuck for 11s! [jfsCommit:2122]

This is my 3ware RAID controller:

02:01.0 RAID bus controller: 3ware Inc 9xxx-series SATA-RAID
Subsystem: 3ware Inc 9xxx-series SATA-RAID
Flags: bus master, 66MHz, medium devsel, latency 72, IRQ 21

This is my mountpoint with a JFS filesystem:

/dev/sda1 on /backup type jfs (rw,noatime,nodiratime)

/dev/sda1 9.1T 4.7T 4.5T 51% /backup

jfs_tune -l /dev/sda1
jfs_tune version 1.1.11, 05-Jun-2006

JFS filesystem superblock:

JFS magic number: 'JFS1'
JFS version: 1
JFS state: mounted
Aggregate block size: 4096 bytes
Aggregate size: 19530376664 blocks
Physical block size: 512 bytes
Allocation group size: 33554432 aggregate blocks
Log device number: 0x801
Filesystem creation: Tue Mar 11 13:45:04 2008
Volume label: ''

Could be JFS version 1 the problem?

All packages are updated.
