For the record, are these the most current changes you speak of?: (I'm reading through the source, perhaps eventually I'll be able to help more...) http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/arcmsr/ - I am not capable of backporting the changes, + but I will gladly test any changes this with a GENERIC kernel once they make it to STABLE Rocket, .ike
