I've found a problem in acpi.cc that caused not parsing acpi tables properly on my pc. The problem is that there is an incomplete check for usability of xsdt table. According to some documentation on the net value 0 in revision entry in rsdp means that this is acpi 1.0 and xsdt table is not available but this was not checked.
Attached patch fixed this issue for me.
