Description Tim Robertson 2001-09-21 04:10:00 UTC

After cvsuping and rebuilding and installing, my machine crashes on reboot.  
I have to boot off kernel.old.
Here's the last thing I see (transcribed by hand):
...
ppio: <Parallel I/O> on ppbus0


Fatal trap 12: page fault while in kernel mode
fault virtual address	= 0x4006

processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 0 (swapper)
interrupt mask		= net tty bio cam

panic: page fault

Here's the messages output from a successful boot to give you info about my system:

Fix: 

Run RELENG_4_3.

I saw this with -stable a few months ago when I was running RELENG_4, but I assumed it was a temporary instability, so I dropped down to RELENG_4_3.  Seems to be more severe than that.
How-To-Repeat: Simply boot the new kernel

Comment 1 Tim Robertson 2001-09-23 02:05:50 UTC

Figgured out this was due to hardware conflicts.  Booted kernel -c, 
 entered visual config, noted changes to eliminate conflicts, edited 
/boot/kernel.conf, and things worked.  I have no idea why this showd up 
when I upgraded.  

P.S.  Shouldn't visual userconfig write out a kernel.conf file?
