APM/DPMS lockup on Dell 3800
I get this problem both in Linux and Windows, so I won't rule out hardware/bios bugs, but I find that often when my monitor (backlight) gets turned off automatically after a long period of non-use, the computer freezes up. I think it only happens when I've left it that way for a long time, though. If I move the mouse immediately after the screen is blacked, I have no trouble, but if I leave it for a long time, when I get back the monitor won't unblack, ctrl-alt-backspace does nothing, ctrl-alt-delete does nothing, Fn-Suspend, Fn-A don't do anything, and the capslock and numlock keys don't do anything either. I haven't tried reaching the machine from outside yet, but I will if someone wants. Possibly useful note: when the computer is in this state and I remove the (PCMCIA) network card and re-insert it, it does not get reset. This could indicate a complete lockup.

By the way, I now checked the syslog, and I see that the last cron message was logged about an hour before I reset the system. So it looks like a total lockup.
BTW, what does it mean when this gets logged?

This is a problem with the 3Com Ethernet card in your system. There are annoying problems when you try to use this card on a network with a lot of collisions.

I have a Dell Inspiron 7000 with BIOS A15 and exactly the same problem.
(I last observed this problem using linux-2.4.0-test12, though. Now I'm running test13-pre3 and it has not yet occurred.)

Dagnabbit. I forgot to give my kernel version, and now I'm booted into Windows, and can't remember it. It's some 2.2 kernel: whatever comes with Mandrake 7.2.
