git diff that demonstrates what fixed it for me
The GPU reset fails when attempting to suspend. First noticed in 6.16.2 (on
arch) and it still occurs with 6.17.0-rc5. This in the dmesg:
[ 25.934105] amdgpu 0000:2d:00.0: amdgpu: MODE1 reset

I tracked it down to commit 8345a71fc54b which replaces numbers with named
constants, but it has several errors in which named constant is used, and the
two introduced MASKs are the same when only one should include the STATUS_MASK.
Note that the preexisting comment on some of the psp_wait_for actually did not
reflect what the code was doing and that may have caused the error in this
commit.
Restoring the numbers back to the original values solves my problem. To help
out, I have attached the patch I used.
