[Bug 1161754] New: [usb-c] System loses USB NIC in Docking Station at random Times
http://bugzilla.suse.com/show_bug.cgi?id=1161754 Bug ID: 1161754 Summary: [usb-c] System loses USB NIC in Docking Station at random Times Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: oneukum@suse.com Reporter: eich@suse.com QA Contact: qa-bugs@suse.de Found By: Development Blocker: --- Created attachment 828223 --> http://bugzilla.suse.com/attachment.cgi?id=828223&action=edit Kernel log On a laptop (Dell Precision 5520) the 1GB NIC is contained in the docking station which is connected via USB-C. With kernel 4.12.14-lp151.28.36-default this device gets 'lost' at random times. 1. The kernel shows no obvious signs of the device getting lost. The lines like: usb 3-1.4: reset high-speed USB device number 6 using xhci_hcd don't seem to occur when the device gets lost. 2. The network device is no longer disappears from the lsusb output. 3. In the more annoying cases, the network device 'hangs': and 'ip addr' hangs in a 'sendto' to a netlink socket. In other cases, the device disappears from the 'ip addr' output, unplugging and plugging the docking station causes the devices to re-enumerated. NOTE: in the attached log, the re-docking happens after the 202556.480017 timestamp. The issue seems to start once the machine has been suspended and/or redocked after a boot. The issue did not occur on a Leap 42.3 kernel. -- You are receiving this mail because: You are on the CC list for the bug.

You can test disabling LPM

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

Since I've set these, the problem did not reoccur. However, my usage pattern has also change since Covid: I'm not traveling much any more. The problem seemed to have been related to docking/undocking and/or suspending the system. So, with this in mind, I'm not even sure the results of my tests will be conclusive - even if I remove usbcore.quirks=0bda:8153:gk,0424:5807:gk usbcore.autosuspend=-1. In any case, today is the last day for me this year, so this will have to wait till January. I'll leave the NEEDINFO set. -- You are receiving this mail because: You are on the CC list for the bug.

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.

I've now observed twice in a row that the Realtek USB NIC has suddenly disappeared while it was in use. It seems like the problem gets triggered as soon as the system has been suspended at least once since the last boot. Please let me know if you want me to do further tests. I will reinstate the quirk settings from comment #6. Sorry for the delay. -- You are receiving this mail because: You are on the CC list for the bug.
