Well I've been using this update now for a few days.

For my own personal problem (sata_mv stability) I see both positive and 
negative results over both 2.6.15-rc5-mm3 and 2.6.15

First postitive:

The bug I was experiening of a raid array 5 array not being visiable or 
startable due to array disks being not being seen as part of the array 
after a reboot appears to have gone. I say appears to as I can't test 
this %100 due to the negative aspect of this kernel. the array starts 
building - no problems gets about %35 through, and the whole machine 
just hangs total lock up.

The reason this is still positive is because when I reboot the box, the 
unfinished md starts rebuilding again, suggesting that this kernel 
actually sees all the disks in the array after a reboot (which 
2.6.15-rc5-mm3 wasn't)

the hang of the system is pretty fatal though.

I'd be interested in what other people are seeing with this kernel tree.

I'm about to test a theroy of building the array with 2.6.15-rc5-mm3 
which can build the array fine, but it dissapears after a reboot, but on 
reboot I'll reboot into the latest libata-git kernel to see if the disks 
are visible.

thoughts or personal experiences (or requests for info on solving some 
of these problems) welcome.

Thanks,

Matt
