Please report this to the Linux ACPI maintainers and complain to your BIOS vendor.
I think the BIOS basically does not properly support either your CPU or Linux or the combination of the two. :\
The reduction of the shutdown time from 50 min to 5 min makes the situation even worse.
I understand. It should be equally easy to flash an older version of the BIOS using flashrom to get the old behavior back.
