I see lots of these [mostly from page fault], the following one (quick and dirty) works for me.
Is that patch or any other fix being picked up? It's over three weeks now and I'm still seeing those BUGs with the latest 3.8-rc.
None that I'm aware of.
Either this one
https://patchwork.kernel.org/patch/2094501/
or a bit an older approach here
https://patchwork.kernel.org/patch/1972071/
should fix this.
/me looks at Dave
