You can test disabling LPM

usbcore.quirks=0bda:8153:gk,0424:5807:gk,1a40:0101:gk

Wow! Thanks! Do I need to 1a40:0101 as well? This is just an innocent USB2 hub that's connected to the docking station.

to be conservative also add

usbcore.autosuspend=-1

I cannot shut down my laptop today as there is just too much stuff open. I still have these settings on the kernel command line: usbcore.quirks=0bda:8153:gk,0424:5807:gk usbcore.autosuspend=-1 I will remove them (ever since I've added these the problem did not occur any more), install and boot the kernel above and do a few docking/undocking cycles (it appears the problem appeared once the laptop had been undocked). Unfortunately, the issue then showed at random times, but never immediately. So I will try to run with this kernel for a week and get back to you if anything happens. Is this ok? -- You are receiving this mail because: You are on the CC list for the bug.
