    EFI Boot Linux Kernel Hangs mmap


    I'm trying to get my linux computer to boot from EFI, i've tried both the stub and grub version. Stub doesn't get me anywhere except a hang (no screen out put). The grub version, seems to go alright then the computer hangs with the abunch of messages like this with slight varations in the region ID's and the :11 number changes, but the final one before freeze is

    mmap/efi/mmap.c:65: EFI memory region 0xff000000 - 0x10000000:11

    The system is a Intel DH87RL Board with the Latest Bio
    The Kernel is a self compiled 3.10.12 (Known to work in no EFI enviroment)

    Found some issues where others had appeared to be having the same problem but their kernel version were much eariler. And there fixes where patches which I couldn't find, and I'm assuming they made it in to the kernel development anyway.

    I assume you mean EFI "Secure" boot? If so, disable secure boot in the EFI BIOS. Running secure boot systems with Linux is still a work-in-progress...
    Sometimes, real fast is almost as good as real time.

    Nope not secure boot, just standard booting from EFI, locks during the boot secquence.

    I'd suggest compiling a new kernel. Linux Mint claims they have a kernel (Mint 15 KDE) for implementing EFI so it's not impossible.

    I've Compiled 3.10.12, 3.10.14, and 3.11.3, and I have included the EFI Code Option, EFI Stub Option, Relocatable Kerenel Option, GUID and FAT File Systems, EFI Frame Buffer.

    Does it work? And why FAT file system support? Just curious...

    Nope doesn't work. I have FAT in there since the EFI partition is supposed to be FAT32, I didn't figure it would affect the actually loading of the Kernel since all of its information is kept on a ext4 parition, but hey, didn't cost much to compile that in and didn't know what else to try.

    Well, since I haven't had to futz with EFI systems as yet (other than in software/virtual systems), I am basically clueless... Someday (not soon, I hope) I'll have to redress that deficiency in my tech chops!

    Same here. That day will be coming soon though, this rig needs to be updated/replaced. Do they still sell machine without all the EFI/Secure boot junk?

    Check with ZaReason - they sell linux/bsd-only systems.
