Xen devel - Aug 2010 - xen-linux-system-2.6.32-5-xen-amd64: Lenovo R61, kernel boots on baremetel, no boot with xen4 hypervisor‏

Hello list,

I have performed a fresh install (fully updated) of
squeeze amd64 and installed the xen-linux-system-2.6.32-5-xen-amd64 package
with all its dependencies. 

When I restart and tried to boot the linux-image-2.6.32-5-xen-amd64 (pvops
style) kernel on bare-metal my laptop boots fine.

When I use the hyper-visor on the system with the same 
linux-image-2.6.32-5-xen-amd64 kernel, it hangs and does not boot up...

Attached is my grub.cfg and relevant dmesg output (notice the failure messages
start occurring near the bottom).

So, should I be filling a bug for this issue or does anyone on the list have a
better suggestion?


Thanks



-M

So it starts all the way until X starts?
Does it work OK without X? 

Did you try "nomodeset" parameter for the dom0 kernel?

Please can you tell us which exact kernel package version you have
installed? 2.6.32-5 quote above is the kernel ABI version which the same
across multiple kernel packages, from (I think) package 2.6.32-12
onwards up to and including 2.6.32-21 currently in Sid and likely for
some future packages as well.

As Pasi asks please try booting without X. It would also be useful to
try the latest package from Sid, it should install cleanly on Squeeze.

This is a good time to punt work.

nomodeset does not fix the booting issue via the xen 4 hypervisor. Also it
breaks the booting on bare-metal as well.

In which way do you prose I boot my system without X.... 

My default runlevel is 2 according to /etc/inittab

# The default runlevel.
id:2:initdefault:

But I get gdm and gnome DE by default.

Thanks for your help :)

Bastian raised an important part some of patches are hacks. And sure enough
they are :-)

I would love any ideas on how to turn them in upstream material?
