Re: [parisc-linux] long bus walk times on boot up

[Ryan Bradetich <rbradetich@uswest.net>]

Derek or anyone else experience this problem,

Feel free to test out this patch.  This impliments Willy's idea and
seems to work find on linux-2.5.  I can not test this against cvs head
on linux-2.4 since my C200 HPMCs in cpu_idle().

I do not have time to track down the linux-2.4 boot issue right now, but
I will commit this patch once I get C200 to boot cvs head and if
feedback from the patch is good.

Thanks,

- Ryan
