Please don't top post.

I too am having a problem with umass on 7.0-STABLE.  Not quite the same as 
yours, but similar.  During reboots, the umass device cases the kernel to core 
dump and the system reboots.  If I unplug the drive and wait for the system to 
come up to a login prompt, I can login, plug in the drive, watch it's detection 
and then mount it with no problem.

Dont' know what the problem is, but other problems with umass have been 
reported on the STABLE list as well.  I've recompiled my kernel six times now. 
The umass device has gone from unmountable to stable in the OS but still fails 
during boot.
