[Libreboot-dev] my Macbook2, 1 w/ latest libreboot randomly gets stuck in bootloot

[Eric Fontaine]

I bought this Macbook2,1 used off eBay (was listed as a defective because screen and CD broken).  After installing libreboot, it is working nicely as a server, except when I have to reboot, which will sometimes (seemingly randomly about %30 chance) get stuck in a bootloop with message:

"ERROR: Unknown key 0xff detected."

repeatedly displayed for15 seconds or so before repeating the bootloop.  Here's pic:

Anyone else have this problem or have an idea why or how I can debug?  All keys seem to work okay (none are stuck).  Before I installed libreboot, I did a dozen or so reboots with the Mac firmware, which although was slow sometimes, did complete all those boots given enough time.

(P.S. Thanks for all the great work.  I've also been using X60s for past 9 months real smoothly.)
