Yes, please provide a screenshot.  A serial console log with "acpi=off
ignore_loglevel" would be even better.

Is this problem new in 3.1, or is it also present in 2.6.39 or 3.0?

Also, do any other cmdline parmaters besides acpi=off work-around it?
pci=noacpi
maxcpus=1

etc.

thanks,

Please keep all the cc's when responding.  Saves you work, saves us work :)

Summary of what I think you're seeing (please correct if wrong):

2.6.38 (Ubuntu/Mint): works fine, even with no boot args
2.6.38 (Fedora 15): works fine, even with no boot args
2.6.40? (Fedora 15 with upgraded kernel): requires "acpi=off" to boot
3.0.0-12 (Ubuntu/Mint): requires "acpi=off" or "maxcpus=1" to boot.
"pci=noacpi" makes no difference.  with no arguments, panics as in
attached screenshot.
3.1.0-0.rc6 (Fedora 16 live CD): can't find root device, drops to
debug shell, even with "maxcpus=1"

Let's focus on Ubuntu and forget Fedora for now.

The screenshot you sent (attached) has a clue ("EIP: [<00000000>] 0x0
SS:ESP 007b:00000046 CR2: 00000000ffffffff, Fatal exception in
interrupt") but doesn't really have enough context.  I should have
suggested booting with "vga=0xf07".  That will use a smaller font, so
the photo can capture more information.  Can you try that?  You might
have to use a lower jpg quality setting or resave with gimp at a low
quality setting to make the size 100K or less for the mailing lists.

If you can boot 3.0.0-12 with "maxcpus=1", collect the dmesg log and
maybe we can compare it with the new "vga=0xf07" screenshot.

Please use reply-all... it saves work for everybody!

Dunno why vga= doesn't do anything.  But this panic is different from
the first (and probably more useful).  Looks like this problem might
be in the acpi_processor_add() path, which might explain why
"maxcpus=1" makes a difference.

I added cc: to a few people who have recently changed the ACPI processor driver.

Are you able to build test kernels yourself?  If so, you could
sprinkle printks() in acpi_processor_add(), maybe with some
mdelay(100) calls to slow things down.

There's also a "boot_delay=" parameter that supposedly slows down boot
printks.  I haven't had much luck with it myself, but "boot_delay=100"
or so might allow you to get more snapshots of the beginning of the
stacktrace.

I found a report with a serial console log showing a very similar
backtrace here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/807164

Seems pretty clearly related to acpi_processor_get_power_info();
hopefully an expert in that area will jump in and help out.

This is really strange..., it happens when trying to evaluate
_CST on a processor object.
But processor objects are declared:
    Scope (\_PR)
    {
        Processor (CPU1, 0x01, 0x00000410, 0x06) {}
        Processor (CPU2, 0x02, 0x00000410, 0x06) {}
    }
and do not have a _CST func. I got the DSDT from the Ubuntu
bug, you may want to double check:
acpidump >acpidump
acpixtract -a acpidump
iasl *.dat
grep _CST *.dsl

If you have a processor object with _CST function you could
try to reproduce this in userspace by using acpiexec from the
acpica utilities.
acpiexec DSDT.dat
-> methods shows you the available ones
-> execute \_PR.CPU1._CST (or similar possibly triggers some mem corruption?)

Ah, maybe an older acpidump got used and the _CST method of the
object is in a not exported, dynamically loaded SSDT.
This is very likely.

Please use a very recent acpidump:
Hm, Len's ftp directory on kernel.org where latest acpidump was
located is gone?
Latest openSUSE acpica package has everything mentioned above included :)
Could get a problem to feed acpiexec with the DSDT and SSDT.., you may
have to glue them (better ask again then). Best is you run it with valgrind.
bugzilla.kernel.org is still down?

I've put a (hopefully) recent acpidump source here:
ftp.suse.com/pub/people/trenn/acpidump
Should get available in an hour or so.

I expect you see:
"Dynamic OEM Table Load"
message(s) in dmesg and the SSDT which includes the ACPI parts which are
causing this is loaded at runtime. Older acpidump versions were not able
to extract these, the one I put on my ftp account should be able to.

Can you run it and put the output somewhere (related Ubuntu bug?) and
provide a pointer to it, please.
Hm, you could create a bug here:
http://acpica.org/bugzilla
It looks like ACPI code in the _CST function is triggering an ACPICA
interpreter memory bug when it tries to evaluate the func (guessing...).
