Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Ok, I'm sorry if the summary isn't better but for now I can't make up a
better one... Perhaps this isn't kernel related but my experiences show
that it _should_ be.

I've had Dapper on my office workstation for three weeks now, and all
that time it has been somewhat sluggish to use (kernel upgraded a few
times). The best indication of that is that the mouse cursor halts every
time there is disk activity. 'find /' on a terminal (xterm & gnome-
terminal) is a way to demonstrate it (the find output halts at the same
time the mouse cursor halts...). This is a pretty decent hardware and it
works just fine with sarge & breezy. And the fault is possibly not in
the hardware itself, because my test laptop (IBM T22) has the same
problem.

Here are the lspci-outputs in case there's something suspicious.
