i don't recall getting these before. this seems like new behavior. i got 4 of these when downloading 4gb of pictures from a sd card. never in the same place twice. sb600 ohci controller.disk... reset: device is detached it seems that umsrecover -> umsreset -> usbcmd and if(usbcmd(ums->dev, r, Umsreset, 0, 0, nil, 0) < 0){fprint(2, "disk: reset: %r\n");i don't see exactly where it is, but could this be a timeout issue? that's the main difference i see between now and the previous time. turning on debugging might not help. there's just too much of it. sometimes it's many gb of transfer before an error. - erik
If a new problem, it 'should' be a hardware issue. Bits, as you know as well as anyone, do not really 'rot'.
Wots the ambient temperature, device temp, planar temp and surface cleanliness/humidity at the area of the driving silicon and on any sockets/conectors?
And if clean, cool, and well-connected, do the PS rail and signals look clean on a 'scope?
