In fact, it only got worse (the first read now fails). So this is not a good idea, we should leave RTS as it is. > It looks like it got a few more reads into that though before > failing on the status. That's probably just a coincidence. What might be useful now, is to check on this system if nut-2.2.1 is able to keep the connection alive. As Kjell already wrote that this is probably a regression in the kernel, so I don't have high hopes it will. If you really feel like digging into this, running the driver through 'strace' might give some useful info.
