Subject: [BUG 3.18-rc3] kernel BUG at drivers/iommu/exynos-iommu.c:481!
Date: Wed, 5 Nov 2014 19:09:06 -0200 [thread overview]
Message-ID: <20141105210906.GA30193@joana> (raw)
Hi,
I'm seeing the following bug running the current linus tree of today,
it seems this was introduced by the following commit:
commit 6b21a5db36427d54a94091fc26b5890c3d6a8af3
Author: Cho KyongHo <pullip.cho@samsung.com>
Date: Mon May 12 11:45:02 2014 +0530
iommu/exynos: Support for device tree
This commit adds device tree support for System MMU.
Also, system mmu handling is improved. Previously, an IOMMU domain is
bound to a System MMU which is not correct. This patch binds an IOMMU
domain with the master device of a System MMU.

It is failing on a BUG_ON(!has_sysmmu(dev));
