Comment 154 for bug 285392

↑↑↑ I found the solution!

That's again me, my first comment is just above.

When booting, I used flag "noapic" ("nolapic" works too). Seriously, I don't know why it didn't help before, most likely I just forgot to try it and thought I already tried. Or just mixed up it wrongly with "noacpi".

So, the same Debian 6.0.1 (stable), same hardware (AMD 690V chipset and all as above). When grub loads press "e" to manually edit boot options and add "noapic" or "nolapic":

You can add one of the flags permanently by editing the system file /boot/grub/grub.cfg. Find there a line with flags giving to the kernel. Add "noapic" or "nolapic":

After editing this file rebuild the grub using a command "update-grub".

Still I noticed that the error "ataX: softreset failed (device not ready)" appears twice at the very start by the system boot but right after it without any pause system continues to load normally. Also I don't see these errors in dmesg.
