2.6.2-mjb1

2.6.2-mjb1

[Martin J. Bligh]

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.

The first thing I notice is that "make rpm" didn't work, and failed with the 
error code at the bottom of this message. Too bad, since I've been building 
RPMs on a big fast WBEL-3.0 four way Xeon, but have to run them on a humble 
PII-350. Forgive me, I do NOT want to build kernels on the test machine, it 
takes forever and needs a bit of temp space tweaking as well.

Built clean by itself, I just can't move and install it easily.

Does it go away if you revert these two?
