Within the past couple weeks I have an FC3 system which periodically locks up hard occasionally. This has happened about four times so far, and usually happens exactly when I'm clicking and/or dragging on my Firefox's vertical scroll bar. The system locks really hard; all activity stops, cursor doesn't move, network is unresposive, and all control-alt sequences do nothing. This system has been very stable until recently, so I am wondering if it might be related to some recent update. It is running the SMP kernel 2.6.12-1.1381_FC3smp, a single-chip Xeon with hyperthreading. If it matters, the mouse is USB with a scrollwheel, but I've not seen any USB problems before. Has anybody seen anything like this; and is there anything I can do to get more information. Since it happens so infrequently, it's tough to reproduce. BTW, I also have another FC3 system (UP Athlon) which has been experiencing hard lockups every third or fourth day for the past few weeks as well (very stable before that), but it usually locks up when left unattended. -- Deron Meranda
