not much really with F9..

What version of the kernel does/can it build? I've looked at scripts,
it's looking at a local source tree, can we rig it work a remote git? or
maybe use a source tree based on the source rpm layout? I wouldn't have
time till the weekend to look at any of that.

Try to move around some large files and see if the kernel crashes, see
below.

That would work if somebody maintains a kernel and source rpms (repo
maybe?) for an XO kernel. No, that is not ideal.

The livecd based stuff doesn't seem to have this issue, more like the
initrd needs a bit of a sleep while the module loads and finds the MMC
card, or as a module, it sort of broken(see below). 

I have F11's anaconda booting, formatting and installing to the MMC
card, only to have it kernel opps when installing the rpms.  

Thoughts anybody?
