I have several "nightmare" hangs (total freeze, dead keyboard, ither
black or freezed normal screen) on six dial-in terminalservers here. It
has been like this since I left kernel 2.0.29. It can happen once a month
up to twice a day, under low loadavg, from a few users up to 25 users.
Nothing in the logs whatsoever.

It is P5/100-166, Asus P55TP4XE MB.
32 or 64 MB RAM.
1Gb up to 1.6Gb EIDE Quantum HD.
Each have three 8 ports 16550A serial card.
They have diffrent Network cards (SMC -tulip, 3COM -boomerang, -vortex).

Most of the users run ppp. The servers also act web and mailserver for the
users.

The big question is: How the heck do I debug this?

Best Regards
