From what i can roughly tell so far it seems like an resource conflict between acpi and
the pnp requested regions in your patch which result in the acpi_thermal code
to read the wrong (0xff) temperature value and halt the machine, but i might be
wrong on the details since acpi is such a big code chunk to swallow.
I don't see any obvious conflict from the log you posted. For the sake
of comparison, can you post the corresponding dmesg log after you removed
the patch?

The only difference i see is that ACPI finds EC in DSDT in the working kernel
and in the broken case something silently fails. Please find attached the 2 bootlogs
and a disassembled DSDT.

This seems to be the start of trouble...
