Are you sure you tracked it down to INVARIANTS?  Or was it DDB?  Please
try with _just_ DDB and see if you can still reproduce the problem.  If
so, then when it hangs, hit CTRL-ALT-ESC and type "tr".  This will tell
who is hung.

As far as debugging prints, add the following printfs to
acpi_cmbat_get_bif():

    printf("Before getting BIF\n");
    as = AcpiEvaluateObject(h, "_BIF", NULL, &bif_buffer);
    printf("After getting BIF\n");
