Message-ID: <CA+O4pC+bHC1Bo4ERSfos8fL+FdnwXTTu_EE=rfd9eFkY7432Jg@mail.gmail.com> Date: Fri, 27 Dec 2013 18:18:32 +0100 From: Markus Rechberger <mrechberger@...il.com> To: LKML <linux-kernel@...r.kernel.org>, USB list <linux-usb@...r.kernel.org> Subject: Re: [BUGREPORT] Linux USB 3.0 I just got another USB 3.0 bugreport, the entire system crashed. That particular customer already filed a bugreport in November 2013 that his system is in a bad state when using some USB 2.0 media devices which even have opensource drivers built into the kernel. USB 3.0 support with Linux seems to be a disaster with Linux 3.6.12. The affected board is an Intel DH87RL board.
