The following workaround fixes for me:
https://ubuntuforums.org/showthread.php?t=2226734
Here are the steps adapted for systemd:
- Check the output of `ls /sys/bus/pci/drivers/xhci_hcd`. In my laptop I
see "0000:00:14.0 bind new_id remove_id uevent unbind". The goal is
to get the id of the xhci_hcd, for me it is "0000:00:14.0"(which I will
use in the following steps). Also verify that the output shows "bind"
and "unbind" as directory entries. The following commands should be
executed in a root shell
- Create a script to unbind the xhci:
# cat > /usr/local/bin/unbind-xhci << "EOF"
#!/bin/sh
echo -n '0000:00:14.0' | tee /sys/bus/pci/drivers/xhci_hcd/unbind
EOF
# chmod +x /usr/local/bin/unbind-xhci
- Create a script to rebind the xhci:
# cat > /usr/local/bin/rebind-xhci << "EOF"
#!/bin/sh
echo -n '0000:00:14.0' | tee /sys/bus/pci/drivers/xhci_hcd/bind
EOF
# chmod +x /usr/local/bin/rebind-xhci
- Create a systemd service that runs before sleep:
# cat > /etc/systemd/system/unbind-xhci.service << "EOF"
[Unit]
Description=Unbind xHCI Host Controller Driver before sleep
Before=sleep.target
[Service]
Type=oneshot
ExecStart=/usr/local/bin/unbind-xhci
[Install]
WantedBy=sleep.target
EOF
- Create a systemd service that runs after wakeup:
# cat > /etc/systemd/system/rebind-xhci.service << "EOF"
[Unit]
Description=Unbind xHCI Host Controller Driver after wakeup
After=suspend.target
After=hibernate.target
After=hybrid-sleep.target
[Service]
Type=oneshot
ExecStart=/usr/local/bin/rebind-xhci
[Install]
WantedBy=suspend.target
WantedBy=hibernate.target
WantedBy=hybrid-sleep.target
EOF
- Reload systemd
# systemctl daemon-reload

Continued in Bug #1622322.
Seems to be paired with dmesg entries like this on the trusty kernel:

And like this on mainline:

Mainline version fyi:
[ 0.000000] Linux version 4.6.0-040600-generic (kernel@gomeisa) (gcc
version 5.3.1 20160509 (Ubuntu 5.3.1-19ubuntu1) ) #201605151930 SMP Sun May 15
23:32:59 UTC 2016
I also get a similar message about 'Failed to disable LTM' if I just
unplug the device before the breakage occurs.
I've attached lsusb before the breakage occurs (so you can see the
device) from the mainline kernel.
Interestingly it appears the drivers on trusty and wily/mainline are
different (r815x vs r8152) yet still exhibit similar troubles. I'm
still digging around to try and figure out why this doesn't seem to be
working, but I was wondering if you all had any idea what might be
going pear-shaped here.
Thanks!
