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.
Thanks
