I am not sure if the problem is easily reproducible... if needed I'll try with the latest fc7 kernel. The dump listed below was extracted from /var/log/messages and was generated after copying > 1GB of data to a DVD-RAM, udf format. When it seemed to have stopped (after 2 hours!) I issued the eject command. It then seemed to write more data to the disk (possibly part of the data had not been really copied, and it was syncing) and a few minutes after this notice came up. best regards Paulo Nogueira PS please cc replies to me Nov 20 23:30:23 *** kernel: kernel BUG at fs/inode.c:191!
