Please include the console printf that is right about the panic message.
It will say either something about a mangled entry or an isize too
small.  Since this problem is happening consistently for you, but there
seem to be no other problem reports from others, I'd highly suspect that
you have filesystem damage that isn't getting detected by fsck.  I 
assume that you are running fsck in the foreground and not in the 
background, yes?  The easiest solution here might be to figure out which
directory is causing the problem, and just clri its inode and then clean
up the mess.
