Re: C67x00 reset problems

[Grant Likely <grant.likely@secretlab.ca>]

Unfortunately, the 2.6.24-rc3 stuff in my git tree is really old.
I've been getting all of my recent work into mainline.  The CF driver
is in much better shape there.  The c67x00 driver is merged into
mainline, but I haven't tested it at all in the last year so I don't
know how well it will work.

Cheers,
g.
