Dear Maintainer,

With kernel 3.10 the card gets stuck in D3Cold status and bbswitch is unsable to turn the card back on.

Here is the message log output:

Hi Martin,

This looks like an upstream issue. Please collect some additional
information (e.g. dmidecode, acpidump, etc.; running
/usr/bin/bumblebee-bugreport would be best), file a bug report
upstream [1], and let me know the ticket number so that we can track
it here in the BTS as well.

Regards,
Vincent

Marking as forwarded to issue #455 in upstream github tracker because
symptoms seem identical. According to upstream, this is an issue
caused by a combination of linux 3.10 + the proprietary nvidia driver,
so there's nothing we can do to fix this.

Regards,
Vincent
