Hi,
The usb-wwan driver triggers a NULL pointer dereference oops after resume
from system suspend on my Toshiba Portege R500, but since that driver
hasn't changed since v3.5 and it is only used by the option driver, I suppose
that the latter is responsible for that.
This is a clear regression from v3.5, it hasn't happened ever before.
I'll collect some details tomorrow.
Thanks,
Rafael

Known bug, we have a fix for it in the usb-next tree now, it will be
going to Linus in a few days.
If you want, I can dig up the patch for it and send it to you, if it's
stopping other things from working for you at the moment.
thanks,

No, it's not delaying me, thanks!
