The warning is new > and harmless for now, so no need to bisect this (it will point you at > the mm/slab.c change by Christoph Lameter). I knew *that* part. Closer look at drivers/firmware/dmi-id.c indicates that it's likely a busticated DMI field in my BIOS - looking around at the stuff in /sys/devices/virtual/dmi/id I found that the files product_version, board_version board_asset_tag, chassis_version, and chassis_asset_tag are empty (trying to 'cat' them gets just a \n) - the other values all look sane. This looks fishy: #define ADD_DMI_ATTR(_name, _field) if (dmi_get_system_info(_field)) sys_dmi_attributes[i++] = & sys_dmi_##_name##_attr.attr; Should that be making a check that it's not pointing at a null string?
