[Regression bisected] v6.3-rc4 Error scheduling IBs after resume from hibernate

[Julian Wollrath <jwollrath@web.de>]

Hi,

on an AMD Ryzen 5 PRO 4650U / Renoir (amdgpu: added device
1002:1636) I the screen basically freezes and I get the
following errors with kernel v6.3-rc4

[   26.214541] amdgpu 0000:03:00.0: [drm:amdgpu_ib_ring_tests [amdgpu]] *ERROR* IB test failed on gfx_low (-110).
[   26.379624] [drm] ring 0 timeout to preempt ib

I bisected the issue, the first bad commit is
b589626674de94d977e81c99bf7905872b991197 reverting it on top
of v6.3-rc4 also fixes the issue.


Best regards,
