Re: [Xen-devel] issues getting more than 16M ram to be used without oopsing. 1.2 and 1.3-unstable

Sounds great! I'll drop in the Intel then.

The latest fixes that you posted are still showing memory corruption
symptoms. Different point again, so the driver is probably just being
really naughty in how it's using things. 8-P

Since you will have the new IO layer soon I think it may be a good idea
for me to just dig out another card from my pile of parts (accumulation of
15 years of pc upgrades, repairs, etc on my own, and other people's
machines.)  If I tried, I think I could probably make a good 7 or 8
working machines from the pile. Is that scary or what? *grin*

Sounds like I'll have plenty of testing to do once the new IO layer is
released. Any information on the IDE subsystems in the new IO layer? I'd
love to see the same "drop in" capability for IDE drivers. Course with me
knowing very little about this level of things in driver land I may be
asking for the sun. Adam mentioned that the 1.2 version does IDE in a very
non-linux way.

I feel bad for having you spend a couple days chasing the 3com driver
around now. 8-/ Is there anything that I can provide that the xen team can
use? I'd like to see if there are any other ways that I can conribute with
my limited  amount of available time. I'll definitly be allocating some
time to testing various cards and systems once the new IO layer is
released.
