I recently received the 4.1 subscription CD. I have a 486-66 machine
running ppp and serving a printer in a very low usage net. Seemed to
work fine. But, I thought, might as well get in this century. Wrong!
I backed-up all the config files and misc tools, etc. I installed
4.1, not changing any partitions, just enabling newfs. All seemed to
go OK. The errata said boot0 had a bug in it, but, the machine booted
OK. I fetched the new boot0 and installed it.
I made no hardware changes and did not even cycle power on the
machine.
I restored the configuration files and rebooted. Fatal Trap 12.
I removed all the restored configuration. The machine boots OK.
'ifconfig le0 inet 192.168.1.1 netmask 255.255.255.0'
causes a Fatal Trap 12.
Fatal trap 12: page fault while in kernel mode.
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0x0
stack pointer = 0x10:0x32e7d70
frame pointer = 0x10:0x32e7d84
code segment = base 0x0, limit 0xfffff, type 0x1b
DPL 0, pres 1, def32 1, gran 1
processor eflagfs = interrupt enabled, resume, IPLL = 0
current process = 179 (ifconfig)
interrupt mask = net
kernel: type 12 trap, code=0
Stopped at 0:
followed immediately by another trap 12.
Dmesg is attached.
This has to be something simple, but, I can't see it.
