Comment 3 Jurgen Kramer 2006-09-20 18:49:47 UTC 
Unfortunately kernel 2.6.17-1.2647 gives the same result. Booting with 'noapic'
or 'irqpoll' does not help. Any other ways to debug this further? I'd like to
test the MacBook's VT support.
Comment 4 Igor Foox 2006-09-22 14:24:42 UTC 
I can reproduce the same thing on a macbook pro. I'll try to make a screenshot
later today, and attach it for comparison.

Any ideas here?

I finally managed to get xen booting properly on my Macbook, google saved the
day. It seems to be a known problem...just do not use the 'enter' key in GRUB to
boot linux (???).

Maybe the GRUB patch can used for FC?

This report targets FC6, which is now end-of-life.

Please re-test against Fedora 7 or later, and if the issue persists, open a new bug.

Thanks
