Can you enable debug like this: # sysctl vfs.nandfs.verbose=0xffffffff The kernel will start printing a lot of debugging information. With default configuration of syslog this will end up in /var/log/messages. Capture something like 30 seconds of output and post it somewhere. -- Mateusz Guzik <mjguzik gmail.com>
