Content-Type: text/plain; charset="us-ascii" ; format="flowed" Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Running 2.6.12 on AMD Opteron on an Arima HDAMA board with a 3ware 8506 card installed and got the following in the log: Jun 25 15:56:34 [kernel] [53161.700276] PCI-DMA: Out of IOMMU space for 65536 bytes at device 0000:03:01.0 Jun 25 15:56:34 [kernel] [53161.700279] 3w-xxxx: tw_map_scsi_sg_data(): pci_map_sg() failed. Jun 25 15:56:34 [kernel] [53161.700332] SCSI error : <0 0 0 0> return code = 0x70000 Jun 25 15:56:34 [kernel] [53161.700334] end_request: I/O error, dev sda, sector 51296795 This error doesn't seem to be mentioned much in this space. Should it be taken at face value? Is it something simple like IOMMU should be set to a higher value in the HDAMA bios? A kernel bug? Or could it actually be bad physical memory or even a bad card? Does it mean the data integrity on the affected hard drive is compromised? -- Maurice Volaski, mvolaski@aecom.yu.edu Computing Support, Rose F.
