The patchset is meant to be pretty stable, not so much a testing ground.
Main differences from mainline are:
1. Better performance & resource consumption, particularly on larger machines.
2. Diagnosis tools (kgdb, early_printk, etc).
3. Updated arch support for AMD64 + PPC64.
4. Better support for sound, especially OSS emulation over ALSA.
5. Better support for video (v4l2, bttv, ivtv).
6. Kexec support.
I'd be very interested in feedback from anyone willing to test on any
platform, however large or small.

I got the following compile error, it might be caused by the fact that
I'm using gcc 2.95:

The patch below fixes the braindead?#define MODULE.
Additionally, it changes a PCI dependency from an error to a Kconfig
dependency.
