The description of the commit also seems (to my untrained eye) to be consistent with the error reported on the console when the lockup occurs: [ 58.729863] ACPI Error: Aborting method \_SB.PCI0.PGON due to previous error (AE_AML_LOOP_TIMEOUT) (20220331/psparse-529) [ 58.729904] ACPI Error: Aborting method \_SB.PCI0.PEG0.PG00._ON due to previous error (AE_AML_LOOP_TIMEOUT) (20220331/psparse-529) [ 60.083261] vfio-pci 0000:01:00.0 Unable to change power state from D3cold to D0, device inaccessible Hopefully this is enough information for experts to resolve this.Does this ring some bell for you? Do you need any further information from Nick? Regards, Salvatore
Hi Salvatore, Have Nick try using "pcie_port_pm=off" and see if it helps the issue. Does this happen in the latest 6.4 RC as well? I think we need to see a full dmesg and acpidump to better characterize it.
