This is a long standing problem. Andrew Patterson gave a patch on the list:
http://groups.google.com/groups?selm=linux.scsi.1019759258.2413.1.camel%40lvadp.fc.hp.com
Without this patch, 2.4.18 would lock up in a few minutes syncing a software
raid. With the patch, it has been running multiple megabytes I/O a second for
months. And yes it can sync software RAIDs too.
The driver seems to be working for some people without the patch, but the
problem appears so quickly on some systems that it is strange the fix has not
been incorporated yet. In my case, I tested with ISP2200 cards and a JBOD with
Cheetah 10k4 and 10k5 drives.
