Hi,

The error message "Caused by (from SRR1=214b030): Transfer error ack signal"
is everywhere in my (PowerBook G4) messages.log. I checked, and the module 
that cause it is yenta_socket.

That's the messages.log after a rmmod && modprobe (the [...] as for hundred 
and hundred line of the same messages:

I'm using the git 3.2.0-rc1 kernel, but I have the same problem with the 2.6.38.
There's something I can do (apart from blacklisting it, and don't use PCMCIA)?

Thanks
