Bug#607095: linux-2.6: backport 2d9e667e (disable IOMMU for iGFX on some chipsets)
Package: linux-2.6
Version: 2.6.32-29
Severity: normal
Hey,
on some hardware (Dell Latitude E4300 and it seems Lenovo X200, and
quite some others), booting with intel_iommu=on will lead to freezes.
Fedora bug at https://bugzilla.redhat.com/show_bug.cgi?id=538163
indicates some revisions of Mobile 4 series intel chipset don't work
fine under IOMMU, and
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2d9e667e
has be written to disable IOMMU only for graphics chipsets.
It'd be nice to backport the patch to Debian kernel, though as IOMMU is
not enabled by default it won't hit default installs.
Regards,
