This is a good point. I think if we suspect this patch, it would be good to compare
dmesg of kernel cold boot with this patch vs the commit just before this patch, rather
than comparing with 6.12.

Here it goes then:

dmesg for 2e6871a632a99d9 (bad -- patch applied):
https://bugzilla.suse.com/attachment.cgi?id=878297

dmesg for bc2846c7ab029f0 (good -- before the patch, i.e. 2e6871a632a99d9^):
https://bugzilla.suse.com/attachment.cgi?id=878298

(6.11-stable SHAs ^^^)
