Hi,
hardware is a lenovo-T410 with Intel Core-i7 CPU both, kernel-desktop from factory (3.2-rc6) and kerneltest/HEAD (3.2-rc7) get stuck in early boot printing 2 alternating lines scrolling too fast to read, something about dma fault.
kerneltest/stable (3.1.6 and 3.1.7) boot fine. kerneltest/linux-next vanilla 3.2-rc6 oopses somewhere in device_attach/device_add kerneltest/vanilla 3.2-rc7 shows the same thing as the other 3.2based ones
playing with the mobile to get some screen shots I get to read: DRAD: handling fault status reg 3 DMAR: [DMA Read] Request device [0d:00.0] fault addr fffff000
Any hints ?
Does booting with intel_iommu=off makes it boot ?
BINGO ... thanks a million! and now ? known issue ?
