I think there is the Problem. I WAS using the 14F on my system and
ext-fs (NOT ext-2-fs). After Linux 0.99pl7 there is a new driver for the
14F which is supposed to be faster.IT IS VERY FAST (in screwing up my
filesystem). I could easily repoduce the problem with the following
command:

cd /usr ; for i in * ; do (tar cf ${i}.tar ${i} ; rm ${i}.tar) & ; done

It starts running and after few minutes I get lots of error messages and
finally the system crashes. when trying to fix the filesystem i also get
so much errors that there is NO CHANCE to fix it. Iam not sure if there
really is to blame the disk-driver or the controller. I already twice
sent a problem-description to c.o.l.but it either did not get out or
nobody took any notice of it. Anyhow, I am using at the moment a
friend's AHA1542B and I ordered a new AHA1542C. With the AHA1542B I have
no problems at all, hopefully my new AHA1542C will behave the same.

Anybody interested on a used (3 months old) UltraStor 14F ???? :-)
