   I just downloaded 6.0-BETA1-i386-disc1.iso from ftp.freebsd.org and 
installed it. I didn't touch any files since that time. I assume that
all bits on that iso ARE up to date, aren't they? Actually I also saw
the same result under 7-CURRENT, so I just took iso image to make sure
that it isn't my fault...

P.S. The panic which I want to analyze is real. When I mount large (24G)
msdosfs partition with a lot of files and run 'du' against it, I'm getting
repeatable panic "wrong dirclust" (both HEAD and RELENG_6). Under 5.4-RELEASE 
and the same partition all goes OK. I've tried both to do "panic" from the 
kernel debugger and to turn off debugger_on_panic to skip debugger and just 
save the core. Resulting cores are identical in sense that I can't analyze 
them ;(

Sincerely, Dmitry
