Hey.

I've just read on Phoronix about some "serious breakage" bug:
https://www.phoronix.com/news/Linux-6.17-PM-Hibernation-FIxes

A fix is available:
https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git/commit/?h=fixes&id=449c9c02537a146ac97ef962327a221e21c9cab3

TBH, the commit message is a bit unclear to me,... the
bug was apparently inroduced in 6.16 rc5, but only with
some other commit from 6.17 rc1 it became "visible".

Whatever "visible" means here... could be that only then
it started to happen more often or at all.


From the original bug report it seems the original hibernate
image would get somehow currupted, which *could* mean that basically
anything might happen... from a crash to complete data corruption.


Since we already have 6.16, I figured it might be worth to give a heads
up and peraps the fix should be cherry picked ASAP.


Thanks,
Chris.
