Hi,
Does anybody have an idea why the following code fails in the
2.6.21.7Fedora 8 XEN kernel but not in 2.6.18.8-xen ?

Due to this, the whole nvidia driver compilation is failing even though it
works on 2.6.18.8-xen dom0 kernel.
Any ideas on what''s missing in the 2.6.21.7 sources?
Thanks a lot,
Emre Erenoglu

Hi Daniel, Thanks for the quick comment. I understand, then why do you think it is compiling fine under 2.6.18.8-xen and also seemingly working fine since a lot of months on my Xen 3.2 system? (game, video playing, compiz, etc.) Emre On Tue, Apr 15, 2008 at 5:37 PM, Daniel P.
