Is there any chance to fix them in vanilla 3.10.61?
Ted is just testing patches to fix these. You are welcome if you can give
them a try as well (tarball attached). I'm not sure patches will be
backported as far as to 3.10-stable but when the patches get some testing
in mainline, I'll be porting them to 3.12-stable for our enterprise
kernel...
OK i tried to port them to 3.10 but it seems i can't handle this. There
are so many differences. Are there any workarounds possible? Currently
the 3.10 kernel is also completely crashing with this backtrace.
No workarounds I'm aware of. Sorry. When I have patches for 3.12, you can
try porting them to 3.10. That should be an easier task...
Yes i think i'll be able todo this. Any idea when you'll have patches
around?
Thanks,
Stefan
