First some old Ignored(sadly) links to the same bug :

This bug is ASUS VIA MB specific. Asus A7V133, hda hdb empty.

From Alan Cox (alan@xxxxxxxxxx) on 2005-04-07 04:41 EST [reply]
BIOS problem I believe not kernel. We only probe hda/hdb because the BIOS
claims the slot may have a drive on it.

So why kernel probes IDE channel I just ordered him to IGNORE?

almost a minute here :/

Heres how it looks without noprobe :

That one takes almost 3 minutes.

Why kernel probes IDE channels twice? Why it ignores noprobe in the
second probe? How is Asus A7V133 Bios broken (how can I check how its
broken) and how can I fix it?
Please dont ignore this message like kernel noprobe :)

PS:distro Ubuntu 6.06 and 2 random liveCD ones so its not distro specific.
