[Xen-devel] Xen 3.4.0 + Lenny dom0 kernel fails on physical hardware, succeeds on HVM

[Brian Conway <xen@xxxxxxx>]

As a follow-up to this thread
( http://lists.xensource.com/archives/html/xen-users/2009-05/threads.html#00635 
),
I noticed that all my Xen tests succeeded on a Xen HVM, but I have the
same boot problem on physical hardware (Gigabyte GA-EP35-DS3L
motherboard).  People reported the 2.6.18.8 kernel from source works, but
it would be great if anyone had ideas for this previously good kernel.
Both systems are running the latest Debian Lenny AMD64 with kernel
2.6.26-2-xen-amd64.  Among other things, I notice the "boot video device"
line is missing.
