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. Kexec support. 4. ivtv drivers
I'd be very interested in feedback from anyone willing to test on any platform, however large or small.
