Fedora 10 unable to boot after updating XO-1 to 8.2.0

[Todd Robinson]

As some of you may know, we (On-Disk.com) do the Fedora 10 SD cards 
which are currently available for the XO-1, but which we will need to 
discontinue.

Currently the Fedora 10 SD cards no longer work after updating to 8.2.0 
(OpenFirmware CL1 Q2E41 Q2E).  When inserting the SD card it acts as if 
it's not inserted, except that it also doesn't attempt to boot Sugar. I 
suspect the olpc.fth is used a bit differently with the newer firmware 
version.

For informational purposes, the Fedora 10 SD cards work fine under older 
XO-1 firmware. The XOs also boot Xtra Ordinary fine after updating to 
8.2.0 but do not work with older firmware versions. (see: 
http://on-disk.com/product_info.php/products_id/881 - should be an 
article tomorrow at OLPC News).

I would love to be able to offer a Fedora 11 option, but from tracking 
this list there doesn't seem to be a version ready for public 
consumption (please correct me if I'm wrong). So this gives me three 
choices:
1. discontinue offering Fedora 10 on SD cards for the XO-1 and rely upon 
non-fedora XO options such as Xtra Ordinary and DebXO which run fine 
with the newer 8.2.0 os/firmware.
2. Continue to offer it, but warn that it must be used with older 
Firmware versions. (I would actually rather just discontinue it)
3. Find a fix to allow F10 to boot on the newer os/firmware.

Any advice or work-arounds anyone may have would be very much 
appreciated. I'll append the Fedora 10 /boot/olpc.fth in case it's helpful.


Thank you,
Todd
