Hi Christian,

> I am running into some usb problems with coreboot & seabios:
I have similar problems with Geode GX2.
Kevin has helped me doing some debugging. (see archives)
It has been a while but i recall having memory corruptions while using
SeaBIOS.
With coreboot alone i had no memory problems.
I used a patched memtest86+ for testing.
See attached patch.
You have to adapt it to LX. (see memtest86 without the +)
Succes, Nils.
