ACPI SPEC define:
_PSV : thermal zone object that returns Passive trip point in tenths of digress Kelvin.
_ACx: thermal zone object that returns active cooling policy threshold values in tenths of degrees Kelvin.
I suspect , when hang, the system was trying to start active cooling with Fan in function acpi_thermal_active that was somehow conflict request with _PTS's call to SMPI in BIOS. So, the solution is :
Disable active/passive cooling request before suspend.
To verify this, please hack acpi_thermal_active.
We need a suspend/resume method for acpi thermal to cleanly solve your problem.
