Seems to be worse now. Compiling with gcc-4.1 because that is the latest
version of gcc we can get on this old system without having to go
wholesale LFS on it. Upgrading alsa and jack is a big step for this
machine. If this is in the too hard basket I'll compile a new kernel
instead.

Now seeing the following errors from dmesg:
