Hi, I'm currently playing around with the ext2 filesystem, and the system has become a little unstable :) With the modified filesystem, processes sometimes hang (state being UNINTERRUPTABLE). I think a buffer_head or a page is locked somehow. I'm wondering if there's any good way to debug this. I'm currently using kgdb, and I'm wondering if there's anyway I can find which buffer_head or page due to which the process hangs. Any suggestion will be appreciated. - Hai -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
