Testing results:
dell Insp. 3500

no pc cards, GENERIC kernel, 1.0A release

I. acpi on
A. no disable flags
1. wall power
a. boot
-- mostly stops, sometimes boots. an instance of running rc, then stopping.
b. boot -s
-- consistently makes it to /bin/sh prompt
2. battery power
a. boot
-- mostly stops, sometimes boots
b. boot -s
-- consistently gets to /bin/sh

  B. 'set debug.acpi.disabled="cmbat"
    a. boot
      -- boots consistently

  C. 'set debug.acpi.disabled="thermal"
    a. boot
      -- stops

  D. 'set debug.acpi.disabled="pci"
    a. boot
      -- starts rc, then hangs dead

I would say it is in 'cmbat' or something that does not get done when it is disabled.
It also seems timing related (may interrupt) because of the inconsistency of the hangs.

Hope this helps.

Attached dmesg, hope it helps. As an aside, this machine does not boot
with ACPI enabled; I made a previous post about it. It is a Dell
Inspiron 3500 (laptop).

Can you try setting the kernel environment variable debug.acpi.disabled from the boot prompt as I posted earlier on this list? The value is space-separated list of one or more of the following keywords.

acad bus button children cmbat cpu ec
isa lid pci pci_link sysresource thermal timer

pci, thermal, cmbat have been reported to be the problem, so you may
want to try them first.
