Message-ID: <f816628b-a4b6-4a53-867e-12e75bc7b4de@exht1.ad.emulex.com> Date: Thu, 12 May 2011 11:41:03 +0530 From: Sathya Perla <sathya.perla@...lex.com> To: <netdev@...r.kernel.org> CC: Sathya Perla <sathya.perla@...lex.com> Subject: [PATCH net-next-2.6 2/2] be2net: fix mbox polling for signal reception Sending mbox cmds require multiple steps of writing to the DB register and polling for an ack. Gettting interrupted in the middle by a signal breaks the mbox protocol. So, set the task to UNINTERRUPTIBLE for mbox polling.
