While I was trying to reproduce mid.gmane.org/976091924.20150415170808@xxxxxxxxxxxxxx on my AMD machine I reproduced this - stock Linux v4.0 and stock origin/staging (df9f5676b3711c95127d44e871ad7ca38d6ed28a). However only if I am using upstream QEMU. If using qemu-traditional I don't see it. Here is my serial log for records (since the line number changed).
