folks,
I''m trying to satrtup xen-unstable with linux kernel-2.6.7
but seems I need little bit more luck.
[Symptom]
- got kernel pacnic in the boot process.
It says
..(snip)
> Kernel command line: /xen/vmlinuz-2.6.7-xen0 root=/dev/sda3 ro
console=tty0 console=ttyS0

I attatched full boot log as "xen-2.0-k267.log".
- kernel 2.4.26 looks OK. Please refer attached file
"xen-2.0_k2426_boot.log".
- Xen DemoCD v1.2 works fine as well.
[I did]
- use vanilla 2.4.26, 2.6.7 kernels
- make world
- make linux26
to create all xen, -xen0, -xenU kernels
- xen-unatable was pulled yesterday (7th Aug).
- add boot option "ignorebiostables", "noacpi" but no help
Any advice to step forward would be very appreciated.
Thanks very much.
Best regards,
Daisaku

Please can you edit select_idle_routine in arch/xen/arch/kernel/process.c to remove the if clause at the top of the function. Christian may be able to suggest a cleaner fix, but I think that should do it. Thanks, Ian ------------------------------------------------------- This SF.Net email is sponsored by OSTG.

Christian, Ian, great! the new bk pulled unstable tree is working like magic. Ah, and yes, the target CPU is LGA775 Intel-P4. Just one thing, still I can see a line "Unknown boot option `/xen/vmlinuz-2.6.7-xen0'': ignoring" in the boot sequence, though it looks no harm so far. It is no problem, right? Thanks very much.
