1) Problem with NTFS (read-only) after upgrade 2.1.131->2.2.1
2) I used to make backups of my NT-Filesystem with a command like:
cd /win-nt;find . -newer /etc/backup/sda5.ref ! -type d | \
tar -c -l -T - -f - | bzip2 >$FILE.$SUF
After a kernel-upgrade from 2.1.131 to 2.2.1, "find" ends with a
Segmentation fault, the klogd writes some messages which you can find at
point 5), and unmounting of /win-nt is no more possible (device busy)
3) keywords: ntfs, module, NULL pointer dereference
4) Linux version 2.2.1 (root@gaston) (gcc version 2.7.2.3) #1 Fri Feb 19
