Better don't use the boot parameters. Try to identify at which point
the culprit might lie and then embed the code you like to
debug in the sources into:
acpi_dbg_level=0xXY (whatever debug level, avoid mutex and other
                        unnecessary stuff you don't need)
... bad code to debug

acpi_dbg_level=0xF

I expect the output will never end, there will pop up an acpi interrupt
or some polling is done by ACPI and you are trapped in endless output...
