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.
