Hmm.  Are those boxes uniprocessor running SMP kernels?

The kernel is SMP.

ASUS X61S is 
 CPU0: Intel(R) Core(TM)2 Duo CPU     P8700  @ 2.53GHz stepping 0a

F50SV has 2 CPU's too according to dmesg:
[    0.000000] Processor #0 (Bootup-CPU)
[    0.000000] Processor #1
[    0.000000] I/O APIC #2 Version 20 at 0xFEC00000.
[    0.000000] IOAPIC[0]: apic_id 2, version 20, address 0xfec00000, GSI 0-23
[    0.000000] Processors: 2
[    0.000000] SMP: Allowing 2 CPUs, 0 hotplug CPUs

ASUS N51JQ (occasional shutdown hang) has:
CPU0: Intel(R) Core(TM) i7 CPU       Q 740  @ 1.73GHz stepping 05
[    0.132435] Booting Node   0, Processors  #1 #2 #3 #4 #5 #6 #7 Ok.
[    0.768809] Brought up 8 CPUs

OK, so it's not the case I was thinking of.  Ohwell.

At this point I guess it's best to open a bug entry in the kernel Bugzilla,
against ACPI (although ACPI may be a red herring), and put some system
information (ie. dmesg outputs from working kernels, if any, outputs of
acpidump) -- or links to where it can be found.

Thanks,
