Message-ID: <54E1FFFA.1060403@compro.net> Date: Mon, 16 Feb 2015 09:34:34 -0500 From: Mark Hounschell <markh@...pro.net> To: "linux-scsi@...r.kernel.org >> SCSI development list" <linux-scsi@...r.kernel.org>, Hannes Reinecke <hare@...e.de> CC: linux-kernel@...r.kernel.org, iommu@...ts.linux-foundation.org, Joerg Roedel <joro@...tes.org> Subject: BUG: SCSI aic7xxx driver and AMD IOMMU Kernel 3.18.7 (x86_64) with an enabled IOMMU. This happens immediately after unloading the aic7xxx driver. In fact this happens unloading any module associated with any pci card on the same bus as the Adaptec AHA-2930CU card. If I blacklist the aic7xxx driver the problem never shows. If I disable the IOMMU, the problem never shows. This was brought up over at iommu@...ts.linux-foundation.org in this thread. http://lists.linuxfoundation.org/pipermail/iommu/2015-February/012274.html and they think it is not an iommu problem, but a possibly a problem with the aic7xxx driver. Complete dmesg attached.
