FreeBSD XXXXX 8.0-STABLE FreeBSD 8.0-STABLE #8 r205349M: Sat Mar 20 00:02:49 EDT 2010     root at XXXX:/usr/obj/usr/src/sys/INSPIRON  i386

I started getting zpool corruption errors, and the console was displaying error messages concerning CACHE problems and SCSI error (20,0).  Unfortunately I recompiled for this quirk and no longer have the actual error message:

camcontrol devlist:
<ST350083 0A 3.AA>                 at scbus2 target 0 lun 0 (da0,pass1)

usbcontrol list:
ugen4.5: <Mass Storage Device Prolific Technology Inc.> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON

I never had this problem as a UFS drive.  Only started getting this message after adding to a zpool.
Recompile w/ the following changes:
