I had a kernel Oops on 2.1.110 while trying to get a remote printer bounce
to work (Filters don't run on remote printers, so you have to setup a
bounce, and the remote computer with a 386 and 8megs ram running X with no
swap doesn't cut it).

Dual Pentium 200MHz MMX
Tyan 1653D, Tomcat III
Intel 82439HX, 82371SB chipset
128 megs memory,
NCR53C810 using BSD ported driver
Both IDE and SCSI harddrives
NE2000 compatible ISA
3Com 3c503
gcc 2.7.2.3

Unable to handle kernel NULL pointer dereference at virtual address 00000008
current->tss.cr3 = 014ef000, %cr3 = 014ef000
*pde = 00000000
