[Bug 241307] Re: [Geode SC] [DBE60] kernels >= 2.6.22 fail to boot [A20 interrupt]

[Mart Raudsepp]

If the non-booting happens in combination with etherboot netboot, as found on the DBE60 BIOS, then the problem of non-booting ever since 2.6.23 (perhaps including 2.6.22 in some cases?) is probably related to some low-level loader work in 2.6.23 (involving also the A20 code) in combination with the mknbi created loader code or something along those lines.
If the tftp payload if created with WrapLinux instead of mknbi, we have seen working fine boot of vanilla 2.6.34 kernel on DBE60.

A user found out that:
"Not 100% sure about the cause, but at least mkelf-linux of OpenSUSE mknbi package seemed to hardcode the (empty) initrd option to the image, that stopped the 2.6.22 kernel to start. Workaround was to give empty initramfs cpio file upon image creation, but I found WrapLinux not to have this "effect" and used it successfully instead..." - http://wiki.thincan.org/Talk:DBE60

Perhaps WrapLinux can be tested, and/or the mentioned workaround.
