Hi list, (copied from https://bugzilla.kernel.org/show_bug.cgi?id=80131:) I have a problem with an external HDD USB 3 dock which gets regularly disconnected. It happens on my main computer, but not on an older linux box (with a recent kernel) and is also fine with a Mac OS X, so I believe that the device is OK. Below is a dmesg extract. I mounted the device shortly after s60, and then started to generate some IO (it seems to trigger the problem faster, but I'm not 100% sure). Problems begins at s137-142. At 143.328 the device comes back, I did not mount it this time, and it gets disconnected again some time after.
