Subject: Suggestions for debugging ata_piix and ahci driver failures on Xen pv_ops dom0 kernel (2.6.29-rcX)
Date: Thu, 5 Feb 2009 10:28:43 +0200 [thread overview]
Message-ID: <20090205082843.GD15052@edu.joroinen.fi> (raw)
Hello!
I'm trying to figure out what's wrong with the pv_ops dom0 kernel/patches [1]
causing at least ata_piix and ahci drivers to fail to work.
There was legacy IRQ enabling problem earlier with the pv_ops dom0 patches,
which pretty much prevented the disks from being detected.. but that got fixed.
It could still be something related to Xen/dom0 irq handling..
I'd be glad if someone could take a look at this 2.6.29-rc3-tip pv_ops dom0 kernel boot log
and comment about _possible_ causes for such behaviour of ata_piix and ahci:

In that testing box I have just one IDE hdd attached to ata_piix controller, the AHCI controller doesn't
have any disks attached.
The exact same kernel works OK without problems on baremetal without Xen
hypervisor.
