From 1448d7c6a2ff96d3b52ecae49e2d0f046a097fe0 Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Thu, 29 Jan 2009 00:13:20 +0100 Subject: ieee1394: sbp2: add workarounds for 2nd and 3rd generation iPods as per https://bugs.launchpad.net/bugs/294391. These got one sample of each iPod generation going. However there still occurred I/O stalls with the 3rd generation iPod which remain undiagnosed at the time of this writing.
