Machine: evbarm
>Description:

I upgraded this machine from netbsd-7 to netbsd-8 yesterday and started 
rebuilding all pkgs (only few installed). During the first day and only
moderate disk activity (the pkg rebuild) it "crashed" four times
like this:

"something" went wrong in disk access, I get the "unable to stop EDMA"
error printed on the console and from that point all disk transfers
fail - I have to hard reset the machine.

The messages comes from mvsata_edma_disable():

                if (ms == timeout) {
                        aprint_error("%s:%d:%d: unable to stop EDMA\n",
                            device_xname(MVSATA_DEV2(mvport)), 
                            mvport->port_hc->hc, mvport->port);
                        return EBUSY;
                }
