What I saw was *many* crashes that I couldnt find the source.
They happened when I did ls, save files under netscape, etc.
The lost+found contained THOUSANDs of special files with sizes
of 20 digit number, unknown users etc. When I tried to remove
them as root, it crashed again. Fsck cant finish the check. Quit
after many many errors(I used -y option). I ended up mounting
the fs manually and backing up as many files as I could, followed
by a newfs.
I restricted my fs to under 4G. I still had to do newfs once.
This time nothing in lost+found. fsck still cant do the job.
I am using a Celeron 400. dmesg follows. Only thing I can think
of is that I was also using a win98 with large partition(>2,8G)
enabled. The two seem to disturb each other. I turned that off
now. Could it be a msdos filesystem support issue?
