Description ahlberg 2000-10-14 02:10:02 UTC

When trying to mount or fscsk a 15gb partition from a Maxtor 20gb UDMA100 connected to a Promise Ultra 100 card the kernel panics. I have got some values from nm /kernel | grep : c0237f3c T cpu_switch\n c0237f38 T default_halt. The computer is a Pentium 200MMX.

How-To-Repeat: It happens everytime I try to mount the partition or try to fsck the partition.

To be able to help you debug this problem we need some 
more information. 

Please see the FAQ (http://www.FreeBSD.org/FAQ/FAQ.html) 
section 'For serious FreeBSD hackers only' 
question 'Making the most of a kernel panic' 
for info how you can help us getting the info we need. 

I also belive the output from a verbose boot will be good 
to have. 
This can be found in /var/run/dmesg.boot after a  
verbose boot. 

Please send the info as a follow-up to this PR 
by sending a mail to  
'freebsd-gnats-submit@FreeBSD.org' 
with the subject of this mail as subject. 

Thanks 
Johan
