Dien dobre Jason,
I have one system (7.0) which becomes extremely unstable if I have a
USB drive connected. I usually get a system crash in 10 to 30 minutes
after mounting the USB drive. It has never crashed without the USB
drive attached, and it has never gone for more than three days with it
attached. Usually the failure is much sooner. This was with 7.0-
RELEASE. I haven't checked since I've moved to 7-STABLE.
I have another system (identical software, different hardware) which
is solid as a rock with the identical USB drive attached.
Unfortunately, the crashing system is a small form machine and there
is no way to put in a different USB controller. The USB drive was for
backups, which I now do over the network to the machine that is
working just fine.
Best of luck with this.
