By this time, probably the hosts which should run w. the driver will be
standing all around the world, which makes applying a patch slightly
more interesting... ;-)

As I mentioned in the initial message, I had experimented with
2.6.22rc6; unfortunately

 a) we have some stuff depending on the kernel where<->2.6.22rc6 makes a difference (does not work)
 b) I experienced a hard lockup w. kernel 2.6.22rc6 this morning while
    not really doing something special (file IO, extracting a tar. As
    this was reproducably happening, we retreated from experimenting
    with it now.

Instead, I built[a patch I snatched from a mail communication
you had on 2007-06-20
(Msg-ID: <> )].
I will attach it with this mail, as it is really small and you don't
have to dig around to know what I'm talking about.

As I am no kernel-developer, I am not sure there are no undesired side
effects by applying this patch to this kernel; if you think there are
(could/should be), it would be nice if you could state that, so I'd
refrain from testing with this combination.

By caffeine alone I set my mind in motion, By the beans of Java
do thoughts acquire speed,  hands acquire shaking,  the shaking
becomes a warning, By caffeine alone do I set my mind in motion
