After a week of testing v4.14-rc2, the conclusions remain the same: - System doesn't freeze when booting up and logging in with the dock attached. - Ethernet doesn't connect automatically on boot / after login, manual intervention required. - System doesn't wake from suspend if the dock was disconnected during sleep. - System does wake properly from suspend if the dock was connected during sleep or dock connection did not change at all. - No sudden ethernet disconnects.
I've got also a TB16 dock now: Problems with kernel 4.13.4: - Graphics crash when booting with dock attached, Ubuntu displayed a message asking what to do, but it recovered after selecting low res mode. Interestingly, I managed to log into desktop. - Everything else same as with WD15 dock. Kernel v4.14.rc2: same behavior as with v4.14.rc2 + WD15 dock. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701499 Title: System often freezes or panics if I log in with Dell Dock WD15 connected Status in linux package in Ubuntu: Confirmed Bug description: I'm using Dell Precision 5520 with Ubuntu 17.04. If I first start a Unity session and then connect Dell WD15 USB-C dock with an external diplay plugged in, the system detects it properly and all the things work flawlessly (ethernet, external keyboard, external display, external storage connected to USB on the dock). I can plug-in and plug-out the dock multiple times and it just works. However if I boot the laptop with the dock already plugged in, first I get to the login screen and initially all is ok. Both screens are activated, and I can log in using the keyboard connected to the dock. When I hit "Enter", both screens go blank for a while, then they turn back on and I can see the desktop. A second or maybe two seconds later things start falling apart. When I move the mouse pointer a second after logging, it is kinda "jumpy", the movement is not smooth. The move freezes for a few times. I observed this behaviour only when moving the wireless mouse connected to the USB of the laptop. The builtin touchpad works smoothly. If it was the only issue, this would be a very minor annoyance. Sometimes, after a few short mouse pointer freezes the system starts working smoothly and all is rock stable from that point. However quite often I noticed much worse things happen: 1. The mouse pointer and everything freezes totally after a few seconds from displaying the desktop. It is not possible to switch to the console with Ctrl-Alt-F1. This happens in >50% of logins. 2. Kernel panic. I observed this behavior with stable Ubuntu kernel 4.10.0-20, as well as 4.11.0 - 4.11.8 (which I'm using now, because 4.11.x seems more stable than 4.10.0-x) and also 4.12.rc5 which I tried once. Even if everything goes fine, I noticed the following errors printed in syslog. I'm not sure if they are related, but they look very iffy to me: Jun 30 10:46:23 p5520 kernel: [ 38.391971] DMAR: DRHD: handling fault status reg 2 Jun 30 10:46:23 p5520 kernel: [ 38.391977] DMAR: [INTR-REMAP] Request device [3e:00.0] fault index 1e [fault reason 38] Blocked an interrupt request due to source-id verification failure Jun 30 10:46:23 p5520 kernel: [ 38.472490] xhci_hcd 0000:0a:00.0: remove, state 1 Jun 30 10:46:23 p5520 kernel: [ 38.472496] usb usb4: USB disconnect, device number 1 Jun 30 10:46:23 p5520 kernel: [ 38.472497] usb 4-1: USB disconnect, device number 2 Jun 30 10:46:23 p5520 kernel: [ 38.472498] usb 4-1.2: USB disconnect, device number 3 Jun 30 10:46:23 p5520 NetworkManager[1129]: <info> [1498812383.7510] device (eth0): state change: disconnected -> unmanaged (reason 'removed') [30 10 36] Jun 30 10:46:23 p5520 ModemManager[1076]: <info> (net/eth0): released by modem /sys/devices/pci0000:00/0000:00:1d.6/0000:06:00.0/0000:07:02.0/0000:0a:00.0/usb4/4-1/4-1.2 Jun 30 10:46:23 p5520 NetworkManager[1129]: <info> [1498812383.7537] devices removed (path: /sys/devices/pci0000:00/0000:00:1d.6/0000:06:00.0/0000:07:02.0/0000:0a:00.0/usb4/4-1/4-1.2/4-1.2:1.0/net/eth0, iface: eth0) Jun 30 10:46:23 p5520 kernel: [ 38.552718] xhci_hcd 0000:0a:00.0: Host halt failed, -19 Jun 30 10:46:23 p5520 kernel: [ 38.552721] xhci_hcd 0000:0a:00.0: Host not accessible, reset failed.
