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 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. Phil
