Hello, I compiled a 3.0-rc5 kernel from debian experimental and tried it to boot as dom0. After scrubbing RAM the screen goes black and nothing else happens anymore. The kernel boots without hypervisor and even as domU without problems. All other kernels I have tested up to 2.6.39 works flawless with 4.0.1 (but 2.6.39 lacks blkback, thats why I want to try 3.0). Does Linux 3.0 needs XEN 4.1 or should it basically run with 4.0.1?

In your case it seems, that the kernel at least boots and the system hangs after the kernel has booted. On my system the boot process stops immediately when the hypervisor tries to boot the linux kernel. Would you like to test my kernel? It is a debian package and can be downloaded from http://www.motschke.de/debian/packages.

To answer myself. Linux 3.0 works fine with XEN 4.0.1. I compiled the kernel again and it now boots. The only difference to older kernel versions is, that the screen turns blank when the hypervisor boots the kernel. Don''t know why. That''s why I thought, the kernel does not boot.

Thank you for the hint. I compiled the kernel with the vga patch and now I can see the text on the console. BTW, I looking for a pciback patch for 3.0. Does someone know, if a patch is available?
