[gentoo-amd64] ASUS M2A-VM and kernel 2.6.27

[David Relson <david@osagesoftware.com>]

Hi,

Anybody using an ASUS M2A-VM mobo with a 2.6.27 kernel?  When I
attempt to boot a 2.6.27 kernel, I see the "Loading modules" message
(and messages for loaded modules) and then the boot process hangs.
With a 2.6.25 kernel, after all the module messages boot displays
"Activating mdev".  I've never seen this message with the 2.6.27
kernel.  For that matter, I tried 2.6.26 a while back and had the same
problem.

Anybody know about this problem or what might cause it?

On a related note, a few weeks back I started seeing kernel messages
like:

PCI-DMA: Out of IOMMU space for 8192 bytes at device 0000:00:14.1 
PCI-DMA: Out of IOMMU space for 1536 bytes at device 0000:02:00.0

The 2.6.25 kernel ran fine for several months before these started
appearing, so I suspect a hardware issue.  However, when running
2.6.27's "make xconfig" I noticed there's an AMD_IOMMU option.  I'd
very much like to see if it relates to the messages above.

If you've got an M2A-VM running, perhaps you could share your .config
with me???

Regards,

David
