Viral, Did you happen to apply all the related patches on the 2.6.10 kernel from TI? If not that would be the starting point.

I am using MVL 2.6.10_mvl401 kernel. Being it USB Audio device, it does ISO transfer and this apparently doesnt work if I have CPPI DMA enabled. I know there have been lots of work happened post 2.6.10 kernel and there are certainly many bugs when you enable CPPI DMA. I just would like to know if someone tried to *backport* all recent fixes to 2.6.10. Anyone from MV or TI ? Any help would be appreciated. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
