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 ?

No idea if it known, I would try a bios update if any and reporting a bug. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

Does intel_iommu=igfx_off work as well? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

actually no, that does not help (and would surprise me, the device the error messages are about is the integrated SD cardreader, and I do not have intel graphics but an nvidia chip).

but I've tried the bios update as well, updated from 1.28 to 1.40 released december'11 and that did not change the issue.

IS there any BIOS options to turn on/off virtualization ? if so, try off or On whatever is not the current state. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

yep, disabling VT-d ("directed I/O" sounds pretty close to iommu to me)

That's why I asked.. ;)

did help, after having that setting disabled in BIOS the kernel runs without any extra options.

Either BIOSes are screwed or the kernel is, I actually think both ;-( THis is probably worth a bug report. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

I also have a similar problem ... but the box works booting with nointremap .

The w520 has the nvidia optimus,so both intel and nvidia. If I set it to have both video cards enabled I don't have this issue, but if I set it to nvidia I see the problem. Turning off VT-d and enabling nvidia doesn't reproduce this issue.

what happends if you enable Intel and keep vt-d on ? (optimus is not supported by the kernel anyway....) Having both cards enabled lead to a different problem, battery life goes to hell. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

Same here with a Dell M4600 precision (after reading this threads I get hope to be able to run 3.2)

I believe more in a regression inside the kernel, knowing that 3.1 was working without any trouble. At least I'm running only with the nvidia, but the trouble exist with nouveau and nvidia blob (even new 295.06) I've added manually iommu_intel=on on my bootline time ago, I will now remove it.

ps for Christian Rodriguez, sorry I will never kill my nvidia chipset, and replace it by the intel one. except if I goes to a kernel hacker summit.

I'm a big addicted of wobbling windows, and nouveau can't do it ... :D
