Hi,
There is a dmesg dump below from my Compaq AP550 workstation.
It has 3 WARN_ON() dumps: 1 from acpi layer and 2 from vmap_pte_range()
There is no such thing in 2.6.27-rc4 which I use daily so I assume
it is something in the -mm tree.
It is a Pentium3 SMP machine.
Kind regards,
Krzysztof

That's coming out of the module loader and is a new one. It's the same
warning as the agp one:

I'm suspecting an overactive assertion in the new vmap code?

I wanted only to report. I cannot use the 2.6.27-rc5-mm1 because
the Xorg does not start (hangs) with it. My card is AGP so can it be
related to the warnings?

The third one is interesting because it is "moving". One the first reboot
(the posted was the second) this warning happened when the snd_au8820
module was loaded and there was no warning about ext3.

It shouldn't be, because the old code has that same warning I think.
It also probably shouldn't be the caller, because nothing is using
the new interfaces yet.
I'm sure it must be something wrong with the vmap rewrite patch, but
I'm simply not having any luck reproducing it yet. Is 32-bit a common
theme? (I'm trying to test 64-bit with a greatly reduced vmalloc space,
but I don't have access to a 32-bit compiler just now - travelling).
I might have to send a test-and-report-back debug patch...

OK, would it be possible to test the following patch on the failing
machine(s), and send me the complete dmesg trace afterwards, please?
The patch does a little bit of extra page table checking, and also
prints a trace of operations on the vmap-space.
Thanks,
Nick

Thanks for that, it clearly shows the virtual address allocator
is allowing an overlapping allocation after a vm_unmap_aliases()
call. Unfortunately, my "random" test case happened not to
trigger that... I should have paid more attention to edge cases
rather than just random testing.
Anyway, I hope this fix should solve the problem for you? (it
fixes it here)

Your patch fixes two WARN_ON dumps from my original dmesg (agp
related and module loading related).
The remaining one is the acpi kobject duplication.

Thanks a lot Nick,
