I wasn't seeing these in -rc5-1117.
Am suspecting this commit or related:
commit 9c8573ca6e35f327d53cb46aba017b95e05d8e08
Author: Bob Moore <robert.moore@intel.com>
Date: Wed Nov 12 15:15:29 2008 +0800
ACPICA: Add a mechanism to escape infinite AML While() loops
Add a loop counter to force exit from AML While loops if the
count becomes too large. This can occur in poorly written AML
when the hardware does not respond within a while loop and the
loop does not implement a timeout. The maximum loop count is
configurable. A new exception code is returned when a loop is
broken, AE_AML_INFINITE_LOOP. Bob Moore, Alexey Starikovskiy.

This is a Dell Latitude D820, and didn't seem to have any infinite AML
loops to escape, at least none that I actually hit with previous kernels...

You could try making the max loop count larger, it is a 32-bit value:
acconfig.h
/* Maximum number of While() loop iterations before forced abort */
-#define ACPI_MAX_LOOP_ITERATIONS 0xFFFF
+#define ACPI_MAX_LOOP_ITERATIONS 0x00FFFFFF

That "works", for some sub-optimal value of "works". It does indeed
shut up *some* of the messages, but boot was taking *forever* (or more correctly,
I gave up when it had taken more than 6 minutes to get through the initial
udev and modprobe flurry that usually takes all of 12 seconds or less to
complete.
I'm suspecting that something *else* is busticated in the ACPI code, and
loops that used to complete quickly are missing whatever terminating
condition they had, and the new infinite loop detector is in fact tripping
properly and catching the (newly introduced) error condition?

Adding come cc:s, and a quick recap for those who didn't see it before:
Dell Latitude D820 laptop, x86_64 kernel, and Robert Moore's patch to detect
infinite looping in the ACPI interpreter is tripping, apparently because
something else in ACPI changed and caused loops that used to terminate to
instead hang now. I've been able to narrow it down to something that
hit the linux-next tree between 11/17 (was good in mmotm1117) and 11/26.

I'm still seeing this in -rc7-mmotm1203. For mmotm1126, I bisected it down
to almost certainly being in linux-next already, which makes me wonder why
I'm apparently the only person seeing it.
Here's one of the hanging ACPI calls again:

It isn't just one thing - looks like the battery, video, the sensor for AC/battery,
and the thermal sensor, and probably other stuff, are all affected.
I've got a -mmotm1203 kernel built with CONFIG_ACPI_DEBUG and CONFIG_ACPI_FUNCTION_TRACE
but discovered that booting with log_buf_len=64m still wasn't enough for
even one or two ACPI calls if you turn on *all* the debugging. Anybody have
a good suggestion on what logging levels and layers I should be starting with?
