I have had two hard locks of the kernel until now using this drive;

the 1st while running the dump(1M) (a second dump went fine);
the 2nd while uncompressing the 88 GByte file of such a dump;

this is with
FreeBSD current.Sisis.de 8.0-CURRENT FreeBSD 8.0-CURRENT #5: Sun Jan 10 09:55:14 CET 2010     guru at current.Sisis.de:/usr/obj/usr/src/sys/GENERIC  i386

the 8-CURRENT is from CVS from May, 2009. Are there any know issues with
USB drives on havy load?

Thx
