There is an early boot failure with linux-3.[9,10].??? when booting using uefi on low memory systems.
This seems like it might be hardware specific, I am running on a Lenovo T520, running bios version 1.42, firmware rev 1.36. This seems to be limited to x86_64, as i386 does boot. I build my initram into the kernel image, the following boot line triggers the issue. The issue causes no kernel messages to be printed to screen (looks like the kernel isn't loading at all to my untrained eyes). linux /kernel-3.9.7 mem=300M the following link contains kernel images and vmlinux for both amd64 and the referenced kernel versions http://dev.gentoo.org/~prometheanfire/bugs/471626/ we are tracking the bug here (keep in mind, this is NOT a pax bug) https://bugs.gentoo.org/show_bug.cgi?id=471626 I have tested the following combinations. amd64 - 300M - 3.9.7 - bug hit amd64 - 300M - 3.10-rc7 - big hit amd64 - 16G - 3.9.7 - bug not hit amd64 - 16G - 3.10-rc7 - bug not hit i386 - 300M - 3.9.7 - bug not hit i386 - 300M - 3.10-rc7 - other bug possibly hit i386 - 16G - 3.9.7 - bug not hit i386 - 16G - 3.10-rc7 - other bug possibly hit the pictures taken for the other possible bug hit are located at http://goo.gl/741ub -- -- Matthew Thode (prometheanfire)
