Subject: via-velocity dma-debug warnings again. (2.6.35.2)
Date: Mon, 30 Aug 2010 21:13:49 -0400 [thread overview]
Message-ID: <20100831011348.GA11993@redhat.com> (raw)
I installed the Fedora 14 alpha, which is based on 2.6.35.2, and hit
the following trace..
WARNING: at lib/dma-debug.c:811 check_unmap+0x212/0x59b()

I haven't confirmed it yet, but I have a feeling this is due to c79992fddee28bbd31b35ac297e1068d32930179
Doing a build with that backed out now to test.
