I built 6.2-rc2 with the patch applied. The same black screen problem happenedThanks for testing. As mentioned earlier I was not expecting this patch to fix

patch twice by panicking the kernel with sysrq+alt+c after the black screen
happened. The system rebooted after about 10-20 seconds both times, but no kdump

requested.
the black screen issue. It should fix kernel warnings and IOMMU page fault
related call traces. By any chance do you have the kernel boot logs?
@Baolu,
Looking into lspci output, it doesn't list ACS feature for Graphics card. So
with your fix it didn't enable PASID and hence it failed to boot.
