[    3.486874] ---[ end trace 8d9696618da93a11 ]---

oddly i had this trace with 5.11.9, but that was apparently caused by this:
https://cdn.kernel.org/pub/linux/kernel … og-5.11.10

it was "fixed" with 5.11.10. difference is with 5.11.9 i had a ton of them, but with 5.11.11 its only happening once. do you think its related to that change above? something i should be concerned about?

edit:
to add, it only occurs during bootup.

edit: #2
they're harmless according to freedesktop.
