Subject: Re: Unexpected multihop in swaput - likely driver bug.

Hi Mikhail,

thanks a lot for pointing this out.

Turned out that this is a known issue, but I've forgot to push the fix 
to drm-misc-fixes and just queued it up for the next release.

Please re-test drm-misc-fixes and let's hope there is another -rc before 
the final 5.12 kernel.

Thanks,
Christian.
