Hello, so I've enabled JBD-DEBUG, and unfortunately somebody corrupted inode instead of journal head this time :-( But corruption looks same - somebody wrote 32bit value 1 somewhere it should not... Does anybody have something like CONFIG_DEBUG_PAGE_ALLOC for x86-64?

This time I was not doing anything special, just building new kernel & browsing web. Thanks, Petr Vandrovec
