Subject: linux-next: Tree for March 25

Hi all,

I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/sfr/linux-next.git
(tar balls at
http://www.kernel.org/pub/linux/kernel/people/sfr/linux-next/).

You can see which trees have been included by looking in the Next/Trees
file in the source. There are also quilt-import.log and merge.log files
in the Next directory. Between each merge, the tree was built with
a ppc64_defconfig for powerpc and an allmodconfig for x86_64.

There were a few merge conflicts (fairly trivial) and a couple of build
failures that have been notified.

I have added POWERPC-really-export-empty_zero_page.patch and reverted
async-tx commit 9974693221954ef1019f87d32ae26a0757d2ee85 ("dmaengine: ack
to flags: make use of the unused bits in the 'ack' field") as these are
still needed to make powerpc allmodconfig build (in particular ext4 and
drivers/dma/fsldma.c). These have been reported previously.

We are up to 48 trees, more are welcome (even if they are currently
empty). The influx of new trees has slowed completely. Thanks to those
who have contributed, and to those who haven't, please do.

In particular, I have very few of the architecture trees ....

Status of my local build tests is at
http://kisskb.ellerman.id.au/linux-next. If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.

Thanks to Jan Dittmer for adding the linux-next tree to his build tests
at http://l4x.org/k/.

Subject: [BUG] linux-next: Tree for March 25 kernel oops, when loading mpt fusion driver - regression

Hi Stephen,

Kernel bug is hit while booting up the next-20080325 kernel with MPT Fusion driver built in.This was reported previously
for the next-20080320 kernel http://marc.info/?l=linux-next&m=120601013920868&w=2

I speculate that this might be related to the problem. The fusion
driver was recently flipped to default to MSI enable (previously it had
disabled them). Could you boot it with the fusion module parameter

mpt_msi_enable=0

if it actually boots that will be a good confirmation that MSI is to
blame.

This I suspect is because of a lost interrupt.

And this one looks to be a second bug: The MSI fault path is actually
causing this oops.

It all works using that option.

It sounds like your motherboard might need to be added to the
drivers/pci/quirks.c with quirk_disable_all_msi ... can you try a
different card with MSI just to see if it's something specific either to
the fusion or the location in the system?

Hi James,

Kernel Bug is still reproducible with 2.6.26-rc9-git1 kernel, I tried booting with mpt_msi_enable=0
as boot paramenter, but the call trace remains the same

^^^^^^^^^^^^^^^

If you had successfully specified mpt_msi_enable=0 this line wouldn't
appear.

My best guess is that you incorrectly specified it as a kernel command
line parameter rather than a module parameter.

Hi James,

Sorry my fault :(, the kernel bug is not reproducible after disabling it.

I don't have easy access to the hardware, it's just some lab machine I was
told I could use for unrelated testing. Until this came up I'd never
heard of "MSI", or "Fusion" before, and still don't have much idea about
they are :-)
