Seg fault when syncing Sony Clie 760 with USB cradle

[Peter A. Goodall]

I am running Redhat 7.1 with the 2.4.12 kernel and using xfs.  I have
applied an SGI patch (linux-2.4.12-xfs-2001-10-11.patch.bz2) to run
xfs.  I am using coldsync 2.2.0 to sync and everytime I try to sync it I
get a seg fault.  This causes a kernel panic and I am no longer able to
use the USB port until I reboot.  Below is the end of /var/log/messages:
