hi ard, thanks for the effort!so, your first recommended patch (the memset thing), applied to current mainline (6.8) DOES NOT resolve the issue.
the second recommendation, a revert patch, applied to the same mainline tree, indeed DOES resolve the problem.
just to be sure, i'm attaching the revert patch. as for the information to find the cause:* boot logs - can't really give you as the boot process just stops - i can send you a picture of the screen taken with my phone.
* dmi data - attaching dmidecode output* distro - current arch linux (rolling distro) - attaching list of installed packages with versions
* versions of boot components - should be included in the listing above feel free to send me any patches, i'll be happy to try them out! cheers, R. On 3/15/24 08:42, Ard Biesheuvel wrote:

I'd like to get to the bottom of this if we can. Please share as much information as you can about the system - boot logs - DMI data to identify the system and firmware etc - distro version - versions of boot components (shim, grub, systemd-boot, etc including config files) - other information that might help narrow this down.Also, please check whether the below change makes a difference or not --- a/drivers/firmware/efi/libstub/x86-stub.c +++ b/drivers/firmware/efi/libstub/x86-stub.c @@ -477,6 +477,8 @@ efi_exit(handle, status); } + memset(&boot_params, 0, sizeof(boot_params)); + /* Assign the setup_header fields that the kernel actually cares about */ hdr->root_flags = 1; hdr->vid_mode = 0xffff;Another thing you might try is reverting commit commit 5f51c5d0e905608ba7be126737f7c84a793ae1aa Author: Ard Biesheuvel <ardb@xxxxxxxxxx> Date: Tue Sep 12 09:00:52 2023 +0000 x86/efi: Drop EFI stub .bss from .data section (in v6.6 the commit id is fa244085025f4a8fb38ec67af635aed04297758d)
