I've made a partition, about 1500 MB.
-Boot 2.4.16-->fdisk-->reboot-->boot 2.4.16-->mkreiserfs-->badblocks -n -vv
(no "..accesbeyond of device)-->reboot-->boot 2.4.17-rc1-->badblocks -n
-vv--> no "..access beyond of device"

ls /etc/mtab && reiserfsck --> same results, in 2.4.16 and in 2.4.17-rc1
--my reiserfs partition is now corrupted, there's no difference between
using 2.4.16 or 2.4.17-rc1--

Now I'll compile 2.4.17-rc2 and I'll run reiserfsck --rebuild-tree. I think
this will sove the problem. But nobody knows know why it happened. I'll
try to test if I can reproduce the bug, but I don't think I can.
