Hi,
in some accident caused by wanting to create the .config/compile the kernel for my new laptop (thinkpad t500) before the desperately needed sleeping I activated DMAR...
I don't know if this is relevant, but I though i better report it.
This was on fb478da5ba69ecf40729ae8ab37ca406b1e5be48 - sometime after 2.6.27- rc7
I stumbled over two buglets: First: [ 4184.617392] DMAR:[DMA Read] Request device [03:00.0] fault addr fa946000 [ 4184.617393] DMAR:[fault reason 06] PTE Read access is not set [ 4184.644081] iwlagn: Microcode HW error detected.

Most of the time when this happened, the machine wasnt reacting for 1-3 seconds and had audio buffer underruns, but I also had a hard lockup which I couldnt diagnose so far.

System worked without propblems afterwards.
I think I had also some wierd interaction with ext3 - but I couldnt diagnose this as the machine crashed - there was some filesystem damage afterwards. But I wasnt able to diagnose it properly.

If you need dmesg or so, I will happily provide it - but I can't reboot just now, waiting for some long running work stuff. 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) Subsystem: Lenovo Device 20e0 Flags: bus master, fast devsel, latency 0 Capabilities: <access denied> Kernel driver in use: agpgart-intel Kernel modules: intel-agp
