We are still playing with the VIA fixups, but this may also be VM related.

currently playing with several VM ideas, and potential fixes which might impact overall performance.

Test 2.4.4pre6 that has the VIA fixes but does not have the VM changes

2.4.4-pre6 did only compile when I aplied the '__builtin_expect'-patch. It crashed at boot however, when initializing my onboard raidcontroller (PDC20265 on a MSI K7T Turbo-R). It seems to be the same problem as reported by Manuel A. McLure. So no word yet about the sound distortion-problem being fixed.

Wow! Now it not only boots right, the sound distortion problem also seems to be fixed!!! Great work! However another problem is still here, i see only one of the two ide-channels of the PDC20265.

The PCD20265 crash is fixed in 2.4.3-ac12 and should be fixed in the next -pre.
In the meantime you can apply the following patch from Alan Cox:

There is a possible patch for that in the Red Hat source rpm but its a bit ugly. I need to figure out if it can be cleaned up and get it included into the main tree

I've sent Linus a fix for the PDC20265 crash
