Bug#460597: linux-source-2.6.22: system segfaulted with message: kernel BUG at fs/inode.c:173!
Package: linux-source-2.6.22
Version: 2.6.22-6
Severity: important
The system hangs perhaps once every two weeks, with nothing in the log.
This time I had a DVD-RAM with UDF filesystem mounted on /mnt.
On the command # umount /mnt
the system suffered a segmentation fault, with kernel.log as below.
The crash is not reproducible.
