I think, yes.
I cannot provide the result, because I dont write logs. I'll make sure
they are recorded next time.
I use a script like:
/sbin/mount $2 || (/sbin/fsck -y $2 && /sbin/mount $2)
to mount data disks.

That is a production machine, so I cant experiment with it. It mounts
all disks automatically thru the script.
The machine just halted when I tried to do umount -f on disk that was
using 100% according to systat. After that the machine gone thru usual
boot and checked most of data disks. In 10 minutes after that it
panicked due to error on another disk (not the one I tried to umount).
"Failty" disk was unmounted.

Maybe you write. But now I dont mount with -f. Dont say I cant to
umount -f :)
It's not about me liking -f. There should be some documentation saying
about proper use of softupdates and ide write cache. It's not always
clear even from the sources.
