Yesterdays Update broke Grub(?) [UEFI]

Hi there,

i'm getting quite desperate by now. after my daily "pacman -Syu" my machine won't boot anymore.

I got a quite fresh Arch64 native systemd-installation with Grub as bootloader - installed following this wiki:

https://wiki.archlinux.org/index.php/GR … _PARTITION

Until yesterdays update everything worked just great. Now Grub is stuck on "Loading initial Ramdisk" - even trying Fallback.

I seriously got no idea. Everything looks right to me (?):

Re: Yesterdays Update broke Grub(?) [UEFI]

Do you have more than 4 GB RAM? Solution: Add "mem=4G" to your command line (Press E in GRUB).

See here: Thread

Re: Yesterdays Update broke Grub(?) [UEFI]

Hi,

I have the same problem. After pacman -Suy I rebooted the system, but it don't boot up any more. Hangs on a grub "Loading initial ramdisk ...". I installed linux-lts kernel (booted via archlinux iso), but it also hangs on the same message. My motherboard is Asrock 970 Extreme 3 too.

Any help would be appreciated.

@nobody44: I've successfully booted with mem=4G. It seems really like a kernel issue, thanks.

thank you nobody.

Re: Yesterdays Update broke Grub(?) [UEFI]

Wow, this is a very severe bug. Same problem here. The same workaround also works for me. Downgraded to the previous kernel also works. Without the workaround.
