dmesg from 3.0.1-3 - I don't get as far as interacting with 3.1

kernel-PAE-3.0.1-3.fc16.i686 works
but exactly the same grub2 setup with
kernel-PAE-3.1.0-0.rc2.git7.2.fc16.i686 or
kernel-PAE-3.1.0-0.rc3.git0.0.fc16.i686 fails. It just hangs after grub have loaded initrd and handed over control.

I saw a similar problem on an iMac 64-bit when grub gfxpayload was set. Phcoder made a patch for disabling that in EFI mode. Mjg59 mentioned another approach and kernel changes.

The 3.1 kernels work ok on iMac 64-bit.
Comment 1 Matthew Garrett 2011-08-23 14:22:41 UTC 
Suspect this is the rtc code changes.
Comment 2 Mads Kiilerich 2011-08-24 13:02:13 UTC 
I noticed that the same machine with 3.0.1-3 reports

Oops:efitime: can't read time!

Comment 3 Mads Kiilerich 2011-08-30 13:06:00 UTC 
kernel-PAE-3.1.0-0.rc4.git0.0.fc16.i686 fails too.
