#68 sbp2 segfaults on modprobe

[Anonymous]

Hi. I have 2 external firewire drives, each with
Oxford Semiconductor 1394 to isa FW900 controllers. My
pci card is a VIA chipset. I am using Linux
2.6.0-test8. SCSI_mod, ieee1394 and ohci1394 are built
as modules and are already loaded when I modprobe sbp2.
I immediately get a segmentation fault error and sbp2
shows up when I lsmod. rescan-scsi-bus.sh runs but
does not give any new drives in /proc/partitions.
/var/log/messages gives a lot of information from the
sbp2 segfault. (here it is):

Addendum: If I load (modprobe) sbp2 first, then ohci1394
second (without any other 1394 kernel objects loaded), I
don't get a warning message on the command line, but
/var/log/messages gives:
