Hello,
After upgrading from firefox 5.0.1 to 6.0b5, my machine locks up hard, the
moment firefox is started under Linux 3.0 with Intel IOMMU enabled.
With intel_iommu=off, everything works fine. Likewise, when going back to
firefox 5.0.1, everything works fine. I've managed to capture the following
kernel output via the serial console.
Kernel panic - not syncing: DMAR hardware is malfunctioning

Any suggestions on how to debug what exactly is going wrong?
The board is an Intel DQ35JO with Bearlake-Q chipset. I'm running
xorg-server-1.9.5
xf86-video-intel-2.15.0
libdrm-2.4.25
Below the output of the kernel with intel_iommu=off.

Does intel_iommu=igfx_off work as well?
I've been seeing a few of these with Ironlake chipsets, the reason
firefox does it is probably because it causes the 3D driver to be
used.

With intel_iommu=igfx_off it works as well. Looks like that keeps IOMMU 1
disabled. So the bug seems to be in the register-based invalidation of mappings
in the DMAR engine that remaps igfx. And it must be something that firefox 5.0
doesn't trigger, whereas 6.0 does.
For completeness, here's the relevant dmesg output with intel_iommu=igfx_off.

I'm seeing this all of a sudden on 3.1 kernels. It might be because of
the firefox upgrade to 5.0 that others were talking about. But, it's
quite easy to trigger. Seems to happen in the first 10 minutes of using
the system. I was only able to capture this with netconsole.
I'll try with intel_iommu=igfx_off as well.

I was seeing DMAR issues as well, but I figured it was self-inflicted because
it was due to the NVidia binary driver. Rebooted with 'intel_iommu=off' and it
behaved itself. Basically, I got a flood of messages like these:

If that tells the iommu people something, fine. If it doesn't, that's OK too, I'll
take it up with NVidia.
