You posted to the wrong list. linux-arch is for issue that affect architecture maintainers specifically. [email protected] is the list you want. You also seem to be asking for help with a driver that's not in the kernel tree, with ancient kernels that few developers use anymore, and with only vague details about the actual problem, so chances are slim that anybody will be interested or able to help you. If you publish the driver as open-source and reproduce the problem with a more recent kernel, you'll probably get more help. - To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
