    DX58SO BIOS 5600 vs. Erratum 69 (Interrupt Remapping)

    jmbreuer

      Erratum 69 for the Intel X58 chipset states that (for the context of VT-d) the BIOS should disable that chipset's interrupt remapping capability.

       

      However, the current BIOS SOX5810J.86A.5600.2013.0729.2250 does not do so.

       

      When booting a current Linux kernel (here: 3.10.7), this problem is detected and corrected during boot:

       

      [ 0.009193] WARNING: at drivers/iommu/intel_irq_remapping.c:533 intel_irq_remapping_supported+0x34/0×74()

      [ 0.009333] This system BIOS has enabled interrupt remapping

      on a chipset that contains an erratum making that

      feature unstable. To maintain system stability

      interrupt remapping is being disabled. Please

      contact your BIOS vendor for an update
