Hello. >From time to time I experience problems with external hard drives connected via USB bus to my laptop. An USB device may suddenly go off-line after receiving some amount of data. I use docking station for SATA hard drives and some other usb-hdd boxes and Asus A6J laptop with openSUSE 11.2. None of USB storage devices almost never go off-line on its own will when idle and rare while reading data, but all of them do it very often during writing data to them. I'm not sure if this is a certain bug in USB subsystem of the kernel of a hardware problem, but different kernels work differently in the situation I mentioned above. Recently I tried kernels 2.6.34, 2.6.36, and now I'm testing 2.6.37rc4. As far as I remember, the problem still exists with any of them, kernels below 2.6.30 worked better but they had other problems (pcmcia, etc). The system log and other files recommended for filing a bug report are in the attachment. --- Linux User
