Since no one else is reporting this (at least not that I have seen),
it is probably caused by the graphics chip driver used by Xorg.
What is your graphics chip brand and model?

lspci | grep VGA
01:00.0 VGA compatible controller: nVidia Corporation NV34M [GeForce FX
Go5200 64M] (rev a1)

Using nouveau driver, no xorg.conf.

Looks a lot like Bug 559791.

Yes! An OP posted quiet a bit on this list about this driver.
You might want to search the archives for this driver and
see what the final outcome was (perhaps he filed a bug?).

This can also be caused by the infernal nVidia MCP78S [GeForce 8200] USB
bug present on many Asus mobos. It has bitten me quite hard at the
most inopportune times (my mobo is an Asus M3N78-VM).

The manifestation of it is the mouse or keyboard freezes up and X
starts eating CPU like mad. I think the USB ports stop supplying
data or interrupts and X sits there polling on them. The only way out
I've found is a restart of X. I have been looking for a fix quite a
while but have not been successful. It has bitten many people using
that "OS from the Northwest" so it's not a Linux-specific thing. It
truly appears to be a hardware bug.

I saw the same exact problem as you describe as far back as
2003 or 2004. The system would freeze up after logging in as soon
as I touched the KB or mouse.
The cause of the problem, I was told, was the
irq conflict between the USB devices and the NVidia card.
I recall I emailed Nvidia and complained about their driver
and they could not fix the problem.
Seems after all these years they are still not fixing the problem.

I have a record up time so far on this kernel
(2.6.33.6-147.2.4.fc13.i686) of 21 hours.

Currently I am running with the boot parameter nouveau.noaccel=1 based
on information from the following Bugzilla entry.
