Thanks for the report. To be sure the issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression
tracking bot (note, the version number is not entirely correct, but
things are a bit tricky here, but that version doesn't matter much
anyway in this case):

#regzbot ^introduced v6.1..v6.3-rc
https://bugzilla.kernel.org/show_bug.cgi?id=217170
#regzbot title amdgpu/iommu/: failed to resume
#regzbot ignore-activity

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply and tell me -- ideally
while also telling regzbot about it, as explained by the page listed in
the footer of this mail.

Developers: When fixing the issue, remember to add 'Link:' tags pointing
to the report (the parent of this mail). See page linked in footer for
details.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
