As I wrote in the other message, the kernel is spinning in
acpi_rs_get_aml_length. There are weird resources in the list. For
serial 00:05 there is resource with type and length equal to 0 and for
parport_pc 00:06 there is resource type 58196295 with length of
134284152. See:
acpi_rs_get_aml_length: ffff8801b9f7b380 type=3 len=16
acpi_rs_get_aml_length: ffff8801b9f7b390 type=0 len=0
acpi_rs_get_aml_length: BAD ffff8801b9f7b390 type=0 len=0
serial 00:05: activation failed
dpm_run_callback(): pnp_bus_resume+0x0/0x80 returns -5
PM: Device 00:05 failed to resume: error -5
acpi_rs_get_aml_length: ffff8801b9f7b680 type=3 len=24
acpi_rs_get_aml_length: ffff8801b9f7b698 type=58196295 len=134284152
parport_pc 00:06: activation failed
dpm_run_callback(): pnp_bus_resume+0x0/0x80 returns -5
PM: Device 00:06 failed to resume: error -5

if (!length)
  return error;

makes it resume again with the errors above...
