That access is on the AMD IOMMU. Make sure to disable its driver in the kernel. > RIP: 0xffffffffa14f3bb6 RSP: 0xffffb551c02a0cf0 FLAGS: 2 > RAX: 0xffffb551c0080000 RBX: 0x0000000000000001 RCX: 0x000000003000000b > RDX: 0xffff97694adc0000 RSI: 0x3000000b00000000 RDI: 0x7ffffffffffff003 > CS: 10 BASE: 0x0000000000000000 AR-BYTES: 29b EFER.LMA 1 > CR0: 0x0000000080050033 CR3: 0x00000003cca84000 CR4: 0x00000000003406e0 > EFER: 0x0000000000001d01 > Parking CPU 5 (Cell: "RootCell") > ... > > or mostly > > ... > Page pool usage after late setup: mem 359/978, remap 16517/131072 > FATAL: Invalid PIO read, port: 1771 size: 1 > RIP: 0xffffffff9d8f5f48 RSP: 0xffffb84900127dd8 FLAGS: 93 > RAX: 0x0000000000000000 RBX: 0x0000000000000002 RCX: 0x0000000000000068 > RDX: 0x0000000000001771 RSI: 0xffffffff9e568b80 RDI: 0xffff898449e90498 > CS: 10 BASE: 0x0000000000000000 AR-BYTES: 29b EFER.LMA 1 > CR0: 0x0000000080050033 CR3: 0x00000003d7c1e000 CR4: 0x00000000003406e0 > EFER: 0x0000000000001d01 > Parking CPU 1 (Cell: "RootCell") > ... > > I've attached the system configuration and 4 log files. > > What should be changed in the system configuration? > Port 1771 (0x06eb) is actually not used in the system configuration, is it? The port is actually 0x1771, i.e. hex. The quick solution is to add a PIO_RANGE for it (and for similar ones) to your config. If you want to understand where it comes from and when it's not listed in /proc/ioports (likely), you can use CONFIG_CRASH_CELL_ON_PANIC and study the backtrace that the kernel will then dump on the violation.
