* [Regression?] Linux 5.19-rc5 gets stuck on boot, not rc4 @ 2022-07-05 13:50 torvic9 2022-07-05 16:39 ` Linus Torvalds 2022-07-07 8:20 ` Thorsten Leemhuis 0 siblings, 2 replies; 11+ messages in thread From: torvic9 @ 2022-07-05 13:50 UTC (permalink / raw) To: linux-kernel; +Cc: torvalds Hi, Linux 5.19-rc5 does not boot on my Kaby Lake Thinkpad. rc3 and rc4 were still fine, so I guess something between rc4 and rc5 introduced a regression. Unfortunately, there are no errors or warning messages. It gets stuck quite early on boot, about the time USB is initialized, so less than 1 second into post-bootloader boot. It then just sits there doing nothing - SysRq still works though. I don't have time for a bisect, but I thought I'll let you know about this issue, and maybe someone already has an idea. Some system information below. Root filesystem is f2fs.

There aren't all that many changes in rc5, and your hardware looks *very* standard (all intel chipset, and a Samsung SM961 SSD). And with the lack of details, we'll either need a bisect: > I don't have time for a bisect, but I thought I'll let you know about > this issue, and maybe someone already has an idea. or we'll need more reports.. > Some system information below. Root filesystem is f2fs. Ok, f2fs is certainly unusual, but there are no f2fs changes in rc5. There's some PM changes for i915 ("drm/i915/dgfx: Disable d3cold at gfx root port") and a couple of thinkpad-acpi platform driver updates, so I'm adding a few random people to the cc in case somebody goes "ahh..."

Wild guess, I'm not involved at all in any of the following, I just noticed it and thought it might be worth mentioning: I heard Fedora rawhide added this patch to solve a boot problem that sounded similar to yours: https://patchwork.freedesktop.org/patch/489982/ See also this thread: https://lore.kernel.org/all/fddf5ca6-77dc-88f9-c191-7de09717063c@redhat.com/ A few config option are mentioned there that seem to have an impact. Maybe it's worth changing those or trying that patch. But as I said, I'm not involved, so maybe this is a bad advice.

Thx for confirming. Yes, that patch is in the drm-misc-fixes tree as bf43e4521ff3 and thus will likely be merged with this weeks DRM merge.
