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");
