2.6.1-rc1-mjb1

2.6.1-rc1-mjb1

[Martin J. Bligh]

The patchset contains ... oh hell, anything I feel like putting in it.  
It's meant to be pretty stable - performance should be better than mainline,
particularly on larger machines.

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/2.6.1-rc1/patch-2.6.1-rc1-mjb1.bz2

Since 2.6.0-mjb2 (~ = changed, + = added, - = dropped)

Notes:  

Now includes kexec and the new kgdb-over-ethernet code ... please test!
Sound under xmms, and other code that uses OSS emulation interfaces to
ALSA drivers should sound a whole load better than mainline with this release.

Hi there...

Have you thought in doing a patch-2.6.1-rc1-mm1-mjb1 and continuing to make a
patchset to the -mm sources?

I considered it once, for about 30s - the answer was no. For one, Andrew 
moves way too fast for me to keep up with. For another, he has different 
objectives - he basically runs a testing tree, whereas I want to go for
something more stable, with cherry picked enhancements (mostly performance
and serviceability stuff).

There's a fair amount of common code between the two trees, which I try
to keep pretty much in sync between the two - I pick up changes he makes
from his latest trees, and send him changes I make.

Boo!  ;)

Hopefuly that'll be backed out of Linus' tree.  Since it has caused
regressions.  Has Ram Pai been notified of the hdparm -t regression?

There is an active thread about this on lkml right now.

I'm just wondering how the HT schedular merge is coming? I'm interesting in getting a better/new one for some testing so I wondered how it was coming along with it being ported to 2.6.1-rc1.

Ingo's scheduler crashes on boot for me. I haven't tried Nick's stuff in
a while, but it's pretty extensive, and comes with a lot of stuff that'll
conflict with what I currently have, so not much fun to merge probably.

Does Nick's stuff work for you?
