Could you run following tests:

1) Boot system with following kernel options:
   root=/dev/mapper/sam-root_x86_64 console=ttyS0 loglevel=8 ro pci=nommconf

2) Enable CONFIG_ACPI_DEBUG in kernel config, recompile, install and
   reboot system with following kernel options:
   root=/dev/mapper/sam-root_x86_64 console=ttyS0 loglevel=8 ro \
     acpi_dbg_layer=0xffff0000 acpi_dbg_level=0xffffffff

3) Remove changest 952:f1bad8203efc from kernel, enable CONFIG_ACPI_DEBUG
   in kernel config, recompile, install and reboot system with following
   kernel options:
   root=/dev/mapper/sam-root_x86_64 console=ttyS0 loglevel=8 ro \
     acpi_dbg_layer=0xffff0000 acpi_dbg_level=0xffffffff

Send me all logs and kernel config files from all tests.

If you have any questions please drop me a line.

Daniel
