Title:
Xenial backport of upstream patch breaks arm64 boot
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Xenial:
Fix Committed
Bug description:
The backport of upstream stable commit 05412471beba "bpf: Take return
from set_memory_ro() into account with bpf_prog_lock_ro()"
(linux-6.9.y) for xenial breaks the boot on arm64 machines in security
cycle s2025.01.13. Note that the backport for bionic that was
submitted together with the xenial version to fix CVE-2024-42068 seems
to be fine.
The kernel will hang during or after the EFI stub runs:
BdsDxe: starting Boot0002 "UEFI Misc Device 2" from
PciRoot(0x0)/Pci(0x1,0x3)/Pci(0x0,0x0)
