Description jsuter 1999-09-09 02:20:00 UTC 
Hardware: K6-2-350 (known to be good) @ 100x3.5, SIS530 mainboard w/ 1MB L2 (pcchips "598" v7.0 board) with 2MB shared video ram configured, 128MB PC100 SDRAM, ASIX 10/100 C-net Pro110B card, IBM 14.4GB 7200 RPM configured for DMA mode...

After building a kernel with everything configured properly (at least to the best of my abilities) the system built fine but I forgot to build softupdates.  Rebuilt the kernel including softupdates and it gives the following error on boot (before loading fsck)

Fatal Trap 12: page fault while in kernel mode
fatal virtual address=0xbffffffc
fault code= supervisor read, page not present
instruction pointer= 0x8:0xc01ede88
stack pointer= 0x10:0xc8bf0e88
frame pointer= 0x10:0xc8bf0ea8
code segment= base0x0, limit 0xfffff, type 0x1b, DPL 0, pres 1, def32, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 1 (init)
interrupt mask = [nothing here]
trap number = 12
panic: page fault

then it informs me how much it loves me and reboots in about 15 seconds

Fix: 

no clue
How-To-Repeat: softupdates on 3.3-RC.  Not sure if its due to my specific situation or not, as I do not have additional hardware I can install 3.3-RC on currently.

Much has changed since 3.3-RC; if you can reproduce this on a 
more recent release, then please submit more details.
