Hi Markus,

You're welcome. I'm happy to find someone how is willing to reproduce
the - let's call it - phenomena.

Do you also have the phenomena that the count of pdflush thread
raises?
And that the load is raising?

You have to be fair. If you have massive parallel access on a
SOHO-Disk
also nothing is happening any more. ;-) Probably this disk starts to
burn.
(To make this

Ohh, that's new. I thought it stands for "phenomena". Now, I'm
frustrated. :-))

I would like to hear if this has a positiv (probably p stand s for
that)
effect.

I had this idea too, but Knoppix doesn't ship with a cciss driver when
I
tried it the last time. Probably you find it on the newest DVD.
I don't have a test machine here to try ubuntu.
Anyway, I would like to hear if you find a solution or if someone is
saying that this is "normal".
Best regards
