Thank you for highlighting this to me. As far as I understand things, the critical piece that makes things stuck is LPA2 (52bit address support). I tried disabling this. What I get is: https://salsa.debian.org/helmutg/debvm/-/jobs/9095840 | UEFI firmware (version 2025.11-4 built at 01:31:14 on Feb 17 2026) | Synchronous Exception at 0x47EFE008 Before this change, I only got: https://salsa.debian.org/helmutg/debvm/-/jobs/9076802 | UEFI firmware (version 2025.11-4 built at 01:31:14 on Feb 17 2026) So this seems to indeed make things proceed further, but only so much. Any further ideas? Completely unrelated, I also got: https://salsa.debian.org/helmutg/debvm/-/jobs/9095842 | [ 22.935909] ------------[ cut here ]------------ | 1664 | [ 22.936407] kernel BUG at arch/x86/kernel/alternative.c:2516! | 1665 | [ 22.939517] Oops: invalid opcode: 0000 [#1] SMP NOPTI | 1666 | [ 22.940644] CPU: 0 UID: 0 PID: 311 Comm: (udev-worker) Not tainted 6.18.12+deb14-amd64 #1 PREEMPT(lazy) Debian 6.18.12-1 | 1667 | [ 22.941476] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 2025.11-4 02/17/2026 This one is not reproducible (neither on salsa nor locally). I'm a bit stuck on all these hangs, but qemu seems to be stuck migrating to forky due to this. Helmut
