by Hi.
I thought I would repost this under a different title just in case...
I have a small problem and I'm not sure if it is a bug with FreeBSD 2.2.1
kernel or something I did. With the current kernel I have built - if I
try to execute a script file without setting the 'x' bit the system
crashes with:
"/kernel: panic: ufs_lock: recursive lock not expected"
When I asked Jordan about this he said it had to be an obvious goofed in my
CONF file (though he had no idea what the obvious goof could be) but I can't
find it. I've tried changing a few things and rebuilding but I still can't
find it. The sources I use are off of the 2.2.1 cdrom and are therefore
unmodified (I symlink as oppose to copy them to disk) - the only thing I have
modified is the CONF file which I have appended to this note. If someone
has the interest and time to look at this (or maybe just compile a
kernel using this CONF file and try it on their system) - feel free to flame
me for doing something stupid - but please point out the stupid mistake in
the process....
Some more information - I have been using this kernel for about 4 months
and the above condition is the only one (I know of) which causes it to crash
during this period - but the condition is reproduceable (i.e.,
% cat > /tmp/script
% ^D
% chmod 600 /tmp/script
% /tmp/script
)_
the system is a P100, ASUS P55TP4XE mother board, ncr 810 scsi controller -
ASUS graphic adapter (trio-3), 32mb ram.
thanks,
atk
