    Tracking broken UEFI implementations

    There can be issues with shipping installer images including UEFI. But they're mainly due to crappy UEFI implementations that vendors have shipped. It's fairly well-known that Apple have shipped some really shoddy firmware over the years, and to allow people to install Debian on older Apple x86 machines we've now added the workaround of a non-UEFI 32-bit installer image too. But Apple aren't the only folks shipping systems with horrendously buggy UEFI, and a lot of Linux folks have had to deal with this over the last few years.

    I've been talking to a number of other UEFI developers lately, and we've agreed to start a cross-distro resource to help here - a list of known-broken UEFI implementations so that we can share our experiences. The place for this in in the OSDev wiki at http://wiki.osdev.org/Broken_UEFI_implementations. We're going to be adding new information here as we find it. If you've got a particular UEFI horror story on your own broken system, then please either add details there or let me know and I'll try to do it for you.

    My HP ProBook 6465b ignores boot entries that I set via efibootmgr or bcdedit and always boots this file: EFI/Microsoft/Boot/bootmgfw.efi

    I wrote some more details here: http://homepage.ruhr-uni-bochum.de/Jan.Holthuis/misc/uefi-madness/
