Hi,
I have a Sil3112A SATA controller, which linux works OK
with. It supports RAID (up to 4 devices), but I'm using
BASE option -- only 1 hard drive.
My question is regarding a 15-20 second delay which
normally occurs every time I boot, unless I pass the
options ide3=0 - ide9=0 to fill up the device table. I
think I have to do this because if I do only ide3=0
(where the device would be), it uses ide4, and so on. I
have GRUB set up to do this automatically, but it's not
exactly adequate (,is it?). So I was wondering if
there're any other ways to get the same affect. Is or
could there be an option to simply disable the probing
of the one specific device/channel every time?
Thanks,
Brien

Please try attached patch and send dmesg output (with patch applied).
Patch is against current 2.6-bk tree, but should apply to any recent
2.4.x or 2.6.x kernels.

"ide3=noprobe" doesnt work?
--bartlomiej
Bartlomiej,
"ide3=noprobe" doesn't make a noticable difference, but
I'll tell what happens with the patch when I get home
and am able to try it
(just so you know it may be several hours before I'm
able to reply again)
Thanks much,
Brien

I will get around to adding in the rest of the secret sauce.
I has everything to do with determining the state of the PHY at boot.

Bartlomiej,
I applied this patch on 2.6.0-test4-bk5 just now, and
this is the (I think relative(?) -- tell me if you want
something else) section of dmesg output:

It doesn't seem right. And it actually takes 2-3 times
as long now.
