(Yes, you are right. The bad binary driver just makes it more visible.)

With untainted kernel, I was able to make xmms skip simply by switching virtual
desktops quickly enough.

When ksoftirqd was reniced to zero, it seems to perform fine (at "2" setting).

I would like to ask whether I should do this. Or is it just the other way round
- renicing the ksoftirqd thread "kills" the effect of deferred processing?

Thanks.

Rudo.
