@Cabalbl4, do you mean that it happens when you boot with the power cable unplugged? Or that it crashes when you unplug the power cable after successfully booting? Either way it would be useful to capture dmesg after it happens, if possible.
It might also be useful to have the DSDT from machines affected by this bug. To collect the DSDT, open a terminal and execute the following commands: sudo apt-get install fwts sudo fwts --disassemble-aml Then attach the DSDT.dsl file generated by fwts to this bug.
