| Platform | Dell Optiplex 7050 | OS | AlmaLinux | OS Version | 9.1 |
| Summary | 0000359: Reboot/Poweroff hangs with "block device autoloading is deprecated and will be removed" message | ||||
| Description | Context: AlmaLinux 9.1 updated to latest version (all packages updated, including kernel). Boot and OS installed on a md raid (mdadm) using an SSD (sata) and a NVME module (M2). MDADM is not broken, but it does not behave as expected. Behavior: System hangs for a few minutes repeating this message several times: "block device autoloading is deprecated and will be removed". After a while, the system proceeds to reboot/poweroff. Apparently, there was a modification in kernel (current version of Alma) that was fixed in further versions of kernel (6.x). There is a kernel patch to support block device autoloading (assuming that mdadm will not remove device autoloading very soon - last updates on mdadm code is 1-2 years old). I see the kernel patch as the only alternative for the moment. The patch should enable BLOCK_LEGACY_AUTOLOAD in kernel. | ||||
| Steps To Reproduce | Install Alma 9.1 (latest) on one or more mdadm partitions (both boot and root). Reboot system | ||||
| Additional Information | This behavior was observed on multiple linux distros - all were fixed by either applying the patch or updating kernel to 5.18+ or 6.x | ||||
| Tags | kernel, mdadm, patch, poweroff, reboot, system hangs | ||||

Maybe related to: https://forums.rockylinux.org/t/shutdown-gets-into-an-infinite-loop-rocky-linux-9-1/8106 https://lkml.org/lkml/2022/8/26/846 Then the patch will be: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4c66a326b5ab784cddd72de07ac5b6210e9e1b06 Is this the one you applied? |

Thanks for the updates ! As I see it, there are 2 ways to deal with this issue: 1. Either enable BLOCK_LEGACY_AUTOLOAD in kernels 5.14 to 5.18 (since 5.18 the mainstream of kernel reverted to this option to be ON/YES). 2. Apply the patch you mentioned to not freeze the queue even if the legacy option is not ON. Since the kernel folks re-enabled this option, I would go for the first option. The main problem here is that Alma is still using kernel 5.14 - this will be resolved by itself once Alma will reach kernel 5.18+ As a workaround, i would suggest re-enabling the option for kernels 5.14-5.18 directly in the kernel configure/build of Alma What do you think ? |

In Alma 9.1 (kernel-5.14.0-162.6.1.el9_1), BLOCK_LEGACY_AUTOLOAD is indeed enabled. * Thu Jun 30 2022 Scott Weaver <[email protected]> [5.14.0-120.82.el9] rhel: configs: enable BLOCK_LEGACY_AUTOLOAD (Ming Lei) [2083917] * Mon Jun 27 2022 Patrick Talbert <[email protected]> [5.14.0-120.el9] - block: default BLOCK_LEGACY_AUTOLOAD to y (Ming Lei) [2083917] In the RHEL (therefore Alma) kernels, the version number can be misleading as a great number of patches are backported. |

I now have a 9.1 kernel set that was built with the patch. It is available here: https://toracat.org/test/kernel/4c66a32/ Please test if you can. Note that they are not signed and are offered for testing purposes only. |
