'reiserfsck --clean-attributes' is to cure the problem if you are already
using a kernel 2.6.15 with the bug. To prevent the problem occurring on a
clean system, simply add 'noattrs' to /etc/fstab reiserfs entries before
booting up a faulty kernel. This needs to be done if you upgrade to the buggy
kernel, or if you have run 'reiserfsck --clean-attributes' to clean up. Once
the kernel bug is fixed, the 'noattrs' option won't be necessary any more.
See the above-mentioned bug report for full details.
