[Linux-cluster] GFS 6.0 crashing x86_64 machine


I am having some problems setting up GFS 6.0. I have the src rpms, and
built them against kernel-2.4.21-15.ELsmp on x86_64. The kernel modules
all load, everything seems to build properly. I create the pool device,
am able to create the file system as well. However, when I do the mount
command (mount -t /dev/pool/pool_gfs01 /gfs01) the machine crashes
instantly. lock_gulm seems to be the culprit, however I cannot get any
useful information out of the system about why this is happening. No
logs, just whammo - the system dies instantly.

My platform information is as follows:

Rocks 3.1 (based on RHEL WS 3.0)
Dual 1.4 opterons
Kernel from rpm: kernel-smp-2.4.21-15.EL
kernel source from rpm: kernel-source-2.4.21-15.EL
GFS: GFS-6.0.0-1.2.src.rpm

My dev files look like:

brw-------    2 root     root     254,  65 Jul 31 01:12 hopkins_cca
brw-------    2 root     root     254,  66 Jul 31 01:12 pool_gfs01

Modules are loaded:

gfs                   261792   0  (unused)
lock_gulm              68960   0  (unused)
lock_harness            4048   0  [gfs lock_gulm]
pool                   85760   3

uname -a:
Linux frontend-0.public 2.4.21-15.ELsmp #1 SMP Thu Apr 22 00:09:01 EDT
2004 x86_64 x86_64 x86_64 GNU/Linux

[root frontend-0 root]# pool_tool -s
  Device                                            Pool Label
  ======                                            ==========
  /dev/pool/hopkins_cca                       <- CCA device ->
  /dev/pool/pool_gfs01                    <- GFS filesystem ->
  /dev/sda                         <- partition information ->
  /dev/sda1                                        hopkins_cca
  /dev/sda2                                         pool_gfs01

And when I do the following mount command:

mount -t gfs /dev/pool/pool_gfs01 /gfs01

The system crashes. At the console, there are tons of system calls being
listed, and at the bottom of the screen:

Code: 39 d0 75 f8 85 c9 74 10 8b 44 24 14 39 d0 74 08 8b 44 24 14
Console Shuts up:
   pid: 3547, lock_gulmd Not tainted
RIP: 0010

So... Any ideas on what may be causing this? This seems to be a
supported platform for this tool according to redhat. Has anybody used
GFS 6.0 on this kernel rev on x86_64 and if so, how did you get it to

Other information:
HBA:  QLogic Corp. QLA2312 Fibre Channel Adapter
SAN Switch: Qlogic SANBOX

Thank you for any help you may have!!
