In any case, still b0rked. Hi Borislav, I might have a theory based on above statement. 1) There's a race window between device_shutdown() and syscore_shutdown(). USB device may be returned to BIOS during device_shutdown() and IOMMU units are disabled during syscore_shutdown(). 2) Printing debug messages enlarges the race window, especially when using serial console. Then it triggers warning message "AMD-Vi: Event logged [IO_PAGE_FAULT device=00:12.0 domain=0x0009 address=0x00000000ffffffc0 flags=0x0010]". But I have no AMD platforms to verify this theory. Could you please help to try adding delays between device_shutdown() and syscore_shutdown() in function kernel_power_off()? Regards!
