I think I found the culprit: snd-hda-intel -- this machine "thinks" it has two
sound cards, a "Hewlett-Packard Company IXP SB400 AC'97 Audio Controller" which
uses the snd-atiixp kernel module, and an "ATI Audio device" which uses the
snd-hda-intel kernel module. Prior to 11.0 only the snd-atiixp device was
configured, but 11.0 also auto-configures the snd-hda-intel device. Deleting
the snd-hda-intel device using yast and removing the snd-hda-intel.ko module
from /lib/modules/ allows 11.0 to boot without using either irqpoll or noapic
as a kernel parameter. As a test to see what 10.2 would do if the
snd-hda-intel were configured, I tried to do so on a running system and the
machine hung semi-solid (it was pingable, but the SATA disk had its interrupt
disabled making the machine useless.)
I suspect that the second audio card is not "really" a card which the
snd-hda-intel driver is capable of handling, and it might not even be a sound
card at all, since there are only audio jacks for one card and the snd-atiixp
card has always worked perfectly with the machine (since openSUSE 10.0).
As I see it, there are two separate bugs here:
1. The snd-hda-intel problem, and
2. The fact that the first boot of the installed system does not allow you to
easily add kernel parameters if the first try fails. The user is trapped in a
boot failure loop until he uses a rescue disk to reinstall grub, and manually
edit the menu.lst -- not a situation you want an inexperienced user to have to
endure.
I will try 11.0-Beta2 when I can get it, and I am quite willing to try anything
else with Beta1 in the meantime.
