Hi, > 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 ;( I get the "wrong dirclust" panic once, I have a small kgdb session in this thread [1], this might help, although the panic was triggered from mkdir(2). Unfortunately, I don't have the dump anymore, it consumes too much space to keep all unresolved panic dumps :(.
