None of the BARs are at 0x404000 which seems to be where OpenBSD is trying to load the firmware? I would have to look at the code to figure out exactly what it is trying to do here (and why it fails). Can you also paste the output from `lspci -v`? Just to compare with what is OpenBSD is reporting. > > 0x003c: Interrupt Pin: 01 Line: 05 Min Gnt: 00 Max Lat: 00 > > 0x00c8: Capability 0x01: Power Management > > State: D0 > > 0x00d0: Capability 0x05: Message Signalled Interrupts (MSI) > > Enabled: no > > 0x0040: Capability 0x10: PCI Express > > Max Payload Size: 128 / 128 bytes > > Max Read Request Size: 512 bytes > > > > As for realtek can You send me some guide for using xl console or some > marks for xl dump to find those keys? I'm not sure about QubesOS, but you have to execute: # xl debug-keys 'Mi' # xl dmesg >From the control domain. I'm adding Marek because he can likely provide guidance about how to execute those commands from the control domain. Regards, Roger.
