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. ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/2.6.5/patch-2.6.5-mjb2.bz2 Since the last release (~ = changed, + = added, - = dropped) Notes: ----------------------------------------------------------------------- Now in Linus' tree: Dropped: New: + cpu_shutdown_race Andy Whitcroft Fix up race during tlb_flush_others on shutdown + find_busiest_group Martin J.
