The Problem:
Boot from install floppies, use visual kernel to remove unneeded devices,
set up for FTP install, connects to server copies 3 to 8 of the
/bin distribution and then "panic: syncing disks..." etc.
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x7200720
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc023a19c
stack pointer = 0x10:0xc5b95ddc
frame pointer = 0x100xc5b95dec
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, press 1, def32 1, gran 1
processor eflags = interrrupt enabled, resume, IOPL = 0
current process = 4 (syncer)
interrrupt mask = net tty bio cam
trap number = 12
The hardware:
DEC Prioris LX 5150. (Pentium 150, Adaptec 7850, 1 - Fujitsu M1608SAU
harddisk, SONY CDU 76S CD-ROM with active terminator, 128 MB RAM,
2 - DC21040 net cards)
This machine has never run enything but FreeBSD since 2.1.6 and
did run 3.2 a few months ago.
Things I have done:
Checked and rechecked SCSI IDs, termination etc. Tried removing
64 MB of RAM, installed RAM in different combinations with contact
cleaner.
Installed OpenBSD2.6, rebuilt kernel, rebooted. Installed Pine
from ports collection, played around with it for several days,
OpenBSD works as good as ever.
Tried installing 3.2 from CD-ROM, same result.
