Hi, thanks for digging into the kernel sources and taking time to help investigate this problem. I suggest turning on the following 2 config options and rebuilding your kernel:
ACPI_DEBUG=y The ACPI driver can optionally report errors with a great deal of verbosity. Saying Y enables these statements. This will increase your kernel size by around 50K. ACPI_DEBUG_FUNC_TRACE=y Additionally enable ACPI function tracing - will probably produce a lot of noise and perhaps will be useful to see where the kernel hangs And then rebooting on mains power rather than battery. I will be useful to know what the final kernel messages are before the boot hangs.
