Enabling debugging in the ACPI subsystem will certainly give this
information. AcpiDebugLevel = 0x00FF works nicely, although
a lot of trace info
Does any debug info come out?
Perhaps I was too impatient ... I just assumed it was hung
because it hadn't said anything for a minute after the
Loading initrd message. When I came back to the console
all sorts of messages were streaming past.
I restarted ... the delay is ~10 minutes, the the

That looks good. You'll probably need to increase your dmesg buffer
or send the output to a serial port, since you will get megabytes
of info.
I only have a serial port on this machine ... but all the interesting
output happens before it is enabled ... i.e. is buffered up in log_buf

You may need to selectively enable/disable the debug trace during a
particular call.
I suspect that the problem is happening during the execution of the
ACPICA interface
A 16MB log_buf was enough.
Here is the initial trace up until the unaligned access messages:
Linux version 2.6.16-rc2-zx1-smp ([EMAIL PROTECTED]) (gcc version 3.4.3
20050227 (Red Hat 3.4.3-22.1)) #7 SMP Fri Feb 10 15:17:06 PST 2006
EFI v1.10 by HP: SALsystab=0x3fefa000 ACPI 2.0=0x3fd5e000
You might try removing this code from actypes.h:
/*
* If possible, pack the following structures to byte alignment
*/
#ifndef ACPI_MISALIGNMENT_NOT_SUPPORTED
#pragma pack(1)
#endif
Either this made things worse, or other changes in the base since
my last test made things worse ...
The alignment stuff is based upon __IA64__ or __ia64__, make sure one
of these is set.
__ia64__ is set
