kernel panic during boot for ata trouble

[Ferruccio Zamuner <nonsolosoft@xxxxxxxx>]

Hi,

I've download:
http://chlamydia.fs.ei.tum.de/pub/DragonFly/snapshots/i386/LATEST-Release-1.6.iso.bz2

and I tried it on a old PC with AMD Athlon 700MHz. and Asus A7V mobo.
That mainboard has 2 controllers (one Ultra66 and other Ultra100) and 4 ata channels; I've only one hd ata100 master on ata2 channel.

it enter in kernel panic after some resetting of ata2 channel:
