USB module causing lockups? (Was: Strange lockups in X)

Everything stops, no mouse pointer response or keyboard response.

No. Last night the desktop was locked up and there was no network

I've not really checked as I rarely work without X. This is on my list
of tests to do as I try to track this problem.

I had not tried anything that intensive on either box. I did have this
laptop lockup a coupl of times while running aptitude and doing an
update and then getting packages.
As I mentioned in my original email, I removed the usb-uhci kernel
module from being resident and this laptop has stayed running. The
desktop hardware uses the uhci module and I removed it from being
loaded at boot time. For the first time, the desktop machine stayed
running through the night, so I may be onto something. It may well be
some sort of bug in the low-level USB driver that causes the problem
when it is loaded without any higher-level USB modules. Since I don't
need it loaded all the time, I can load it and unload it when needed.
