I am playing around with my Lenovo Thinkpad X301 and can reproduce a =20

System is 8.1-RELEASE amd64.
Here's the beginning of crashinfo's output, it's full size is >300kb, =20
so please ask me if you want the whole file.

I removed all usb related stuff from the kernel config and use =20
modules. In rc.suspend
I unload the modules.
When I still had the usb drivers inside the kernel suspending worked =20
more reliable.
