We've found that FreeBSD 7.0's support for USB disks is pretty unstable. We 
have a process that creates a bootable FreeBSD 7.0 image on a USB disk and this 
requires writing a fairly large amount of data in one shot to the USB drive. 
We've found that there is probably less than a 50% chance of this actually 
working. More often than not, the write process hangs up and the system has to 
be rebooted to recover from that state it is in. 

Are there any patches available that improve the reliability of this kind of 
mass writing to USB drives. We don't seem to have as much of an issue with 
reading. Once we've created one of our bootable disks for example we can boot 
our systems with them and they seem to work fine. The failures occur when a lot 
of data is being streamed to a USB disk. 

Any suggestions would be appreciated.
