We have recently been experiencing problems with hard lock of FC1 on
three different dual processor machines - 2 Athlon MP and one Intel
P-III.  All have various flavors of NVidia cards.

The machine I am currently on is probably the worst offender - has been
locking up about every 1.5 days for the last 2 weeks.  Can't find
anything in logs after reboot.  Just freezes as described - can't get
any keyboard/mouse response (including ctrl-alt-Fx, ctrl-alt-bksp,
ctrl-alt-del), nor login over the net.

Just turned on the kernel.sysrq = 1 in /etc/sysctl.conf and added
nmi_watchdog=1 to grub as suggested earlier in the thread.

Some info...

The other Athlon machine has a KVM which is sometimes problematic with
mouse craziness, but no apparent correlation with hard lockups.  The
P-III has problems with some screensavers, but also locks when in use.

Am also going to try a standard kernel - we've been running the ATrpms
versions to get NTFS-read support.
