That seems to say that (apart from the VM problem he mentioned)
2.6.0 should in fact perform as well (xrun-wise) as patched 2.4.x, but I
thought some people here have found that it doesn't.
Now I'm back at home (I posted earlier from work) I find that my kernel
that dropped chunks of audio was in fact 2.4.22, not 2.4.20.
Rather than upgrade that to 2.4.23 I've downloaded 2.6.0. This could be
quite an ambitious project for me, as I'll take the opportunity to use
the built-in ALSA drivers to replace the current OSS, and find out
whether they support the S/PDIF input of my M-Audio DIO 2448. Not to
mention all the other things that will be different - having once
been a contented Debian stable user the air seems to getting thin now.

Isn't open source wonderful!
Thanks to all who posted and mailed other suggestions. If 2.6.0 breaks
too many things I will be trying some of them...
Cheers
