Hangs with UFS2 snapshots

[Skylar Thompson]

I'm running FreeBSD 5.4-RELEASE on a dual processor P-III, with 512MB 
RAM and a Mylex AcceleRAID controller.  I'm trying to do live filesystem 
backups to a hot-spare system with UFS2 snapshots. I create the 
snapshots with mksnap_ffs, mount them, and then rsync the data over to 
the hot spare over NFS. I can very reliably cause the system to hang on 
disk requests to certain filesystems, requiring a reboot. I can also get 
this to happen with dump's "-L" option, but have yet to experience it 
with background fscks. Has anyone experienced this, or know of a fix?
