I reproduced with the available versions in debian: linux-image-6.12.12-amd64 6.12.12-1 -> segfault linux-image-6.12.17-amd64 6.12.17-1 -> segfault linux-image-6.13-amd64 6.13.5-1~exp1 -> 'kernel BUG at fs/netfs/read_collect.c:316!' Then I took the debian 6.12.17-1 kernel (latest LTS), added those 3 patches: https://lore.kernel.org/netfs/20250211093432.3524035-1-max.kellermann@xxxxxxxxx/ https://lore.kernel.org/netfs/20250210223144.3481766-1-max.kellermann@xxxxxxxxx/ https://lore.kernel.org/netfs/20250210191118.3444416-1-max.kellermann@xxxxxxxxx/ The resulting kernel apparently fixed the issue, I just testet in Qemu so far (no signed kernel for secure boot).
