3a75dfd3 | 1 | Finally, I debugged it today. The problem is in PNP BIOS. pnp_bus_suspend() |
2 | calls pnp_stop_dev() for the device if the device can be disabled according | |
3 | to pnp_can_disable(). The problem is that pnpbios_disable_resources() | |
4 | returns -EPERM if the device is not dynamic (!pnpbios_is_dynamic()) but | |
5 | insert_device() happily sets PNP_DISABLE capability/flag even if the device | |
6 | is not dynamic. So we try to disable non-dynamic devices which will fail. | |
7 | This patch prevents insert_device() from setting PNP_DISABLE if the device is | |
8 | not dynamic and fixes suspend on my system. | |
