Hi Issac, I can't reproduce this crash if I have slub_debug enabled https://bugs.linaro.org/attachment.cgi?id=1149. But I can still reproduce the crash, with the same build, if I just remove the slub_debug bootarg https://bugs.linaro.org/attachment.cgi?id=1150 Is there any specific (slub_debug=) option(s) you want me to try? May be I can reproduce this bug just with those options. Regards, Amit Pundir > > --Isaac
