Greetings,

I am having this very disturbing and puzzling problem on a Unix Sys V
release 4.0.2.1 system.  The machine has a Consensys Powerports/HD
multi-port serial card in it.  Recently I got a powerports message
followed by a double fault and then a panic.  Consensys sent me a new
driver and their message doesn't come up anymore, but the rest of the
messages still do.  The messages are as follows:

Double Fault
tss386.t_link	0xE0001518
tss386.t_esp0	0x000000E8
tss386.t_ss0	0x08046000
tss386.t_esp1	0x00000000
tss386.t_ss1	0x00000000
tss386.t_esp2	0x00000000
tss386.t_cr3	0x00000000
tss386.t_eip	0x00000000
tss386.t_eflags	0xB51800E7
tss386.t_eax	0xE0008969
tss386.t_ecx	0xB6000807
tss386.t_edx	0xE0008269
tss386.t_ebx	0x00000000

PANIC:

Trying to dump 8127 pages..................................

Reboot the system now.

I did a little poking around and there is an include file call tss.h in 
/usr/include/sys, that has these flags identified.

This seems to happen when about seven people log in and start doing stuff.
The machine can sit idle all night and be fine in the morning until it starts
being used.  The configuration of the system is

Intel 486/50 EISA with 32 MB of RAM
AT&T SCSI card (DPT with an AT&T ROM) with 8.5 MB of SCSI cache
Four SCSI hard disks (1 internal 3 external)
Hayes Fax Board
Adaptec SCSI card running a 8mm tape drive
Powerports/HD multi-ports card (16 ports)

If anyone can give me a hand and explaining this problem I would appreciate
it greatly.
