I have 3.1-STABLE in a fairly hostile network environment. 
I've found that the following will make the system unstable
and reboot. If you avoid all of thses, it's solid as a rock.
(otherwise you get the reboots)

VESA support
VM86 support
OSS/Payware sound drivers

With any of thses, the system will reboot anywhere from a few
minutes to a day or two after being brought up, usually within a few
hours. With all of these removed, it's stable.

The system is a PII/266 192MB with SCSI disks on a Buslogic, a Tulip
(de0) ethernet card, Matrox G200 video, and a Creative Vibra16Xv soundcard.
