--- Comment #1 from Brendan Conoboy <bconoboy at gmail dot com> 2011-12-06 21:02:22 UTC --- This bug is in reference to the patch that Diego Novillo accepted into 4.7 about 10 months ago: http://gcc.gnu.org/ml/gcc-patches/2011-03/msg01477.html The issue is still present in gcc 4.6.x and the same patch resolves the issue. This is a problem for all gcc 4.6-based ARM targets. In Debian, the discussion and resolution is here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=625825 Linaro and Ubuntu use the same patch. Discussion here: https://bugs.launchpad.net/gcc-linaro/+bug/675347 We've been carrying the patch in Fedora-ARM as well. Without the patch applied the USB stack is broken on ARM, as are various KDE/Qt builds.
