http://bugzilla.kernel.org/show_bug.cgi?id=7246 aradford@xxxxxxxxx changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |aradford@xxxxxxxxx ------- Comment #13 from aradford@xxxxxxxxx 2008-02-25 11:54 ------- Javier, The final issue you are talking about (different from original issue in this bugzilla entry): The 3w-xxxx driver calling pci_map_sg() with sc_data_direction == DMA_BIDIRECTIONAL caused data corruption when going through swiotlb.c, on EM64T with 4GB or higher of RAM. AMD64 systems using IOMMU were never affected. This problem doesn't exist in the 3w-xxxx driver in kernels 2.6.23 and higher. The reason is the 'scsi data buffer accessors' patches removed most instances of scsi drivers calling pci_map_sg() and replaced them with scsi_dma_map(). This corrected the problem of the 3w-xxxx driver over-riding the default sc_data_direction that was causing data corruption with EM64T systems with 4GB+ RAM. If you need a driver update for an older kernel to fix this issue, please go to www.3ware.com, however no driver patch to 3w-xxxx needs to be sent to the kernel tree to fix this issue. Please close this BUG. -Adam Radford -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
