--- Comment #12 from Paul Menzel (pmenzel+bugzilla.kernel.org@molgen.mpg.de) ---
@David, please increase the number of retries instead of increasing the delay.
Please also print out the number of retries.

Looking at the patch, delaying the boot by up to 100 ms, and no proper logging,
it leaves a lot to be desired.

@David, you can also test Alex’ patch *iommu/amd: Fix event counter
availability check* [1].
