Dear All, Has anyone got USB OHCI running on a 2.4.2 kernel with a mips r4k processor ? I have successfully used the above with a r3k mips processor but now after porting the same base code to a r4k processor the kernel throws an OOPS. I believe the problem may lay with the writeback cache because when I disable the d cache on the r4k 2.4.2 kernel USB works fine ! I did some digging around and noted that the working aic7xxx driver I have on the 2.4.2 r4k makes use of pci_map_single to handle cache flushing ( ??? please correct me if I am wrong ) and that this type of code doesn't make it into the usb code until 2.4.4 of the sgi linux kernel. Does anyone have a "back patch" to apply to the 2.4.2 usb code ? If not I am thinking of attempting this myself and would welcome any comments / advice about doing this TIA Wayne __________________________________________________ Do You Yahoo!?
