Computer reboots on shutdown related to xhci

woodnt · 05-08-2015, 09:23 PM

Hello,

I have a Lenovo Flex 2 15" with LMDE installed tracking jessie. When I shutdown or halt from the command line or GUI, it will shut off completely, but then after around 3 seconds, it will reboot. The only way I can shutdown, is to hit the power button after it starts to go to the grub2 screen.

Some have had this solved by adding noirq to the startup, but this makes my system unbootable. I tried acpi=off, but that is unbootable as well. I then tried noacpi (which unreliably works).

I have found that if I disable xhci in bios, then the system behaves normally (falling back to ehci). However, this is not a solution I care for, because it prevents me from using USB 3.0 speeds.

I have looked high and low on a solution that will work in my situation, but came up bubkis, including this script:

Code:

#!/bin/bash

if [[ $EUID != 0 ]] ; then
  echo This must be run as root!
  exit 1
fi

for xhci in /sys/bus/pci/drivers/?hci_hcd ; do

  if ! cd $xhci ; then
    echo Weird error. Failed to change directory to $xhci
    exit 1
  fi

  echo Resetting devices from $xhci...

  for i in ????:??:??.? ; do
    echo -n "$i" > unbind
  done
done

found at http://billauer.co.il/blog/2013/02/u...ci-uhci-linux/

I also found this code, which didn't work:

Code:

for i in /sys/bus/*/devices/*/power/control ; do 
     echo on > $i 
done

Any further things to try would be greatly appreciated.

Kind regards,
Nathan

reminds me of my 486 from years. turned out i was setting it up like a server or something. anyway is there alot of server services running for the same task or any services?

Have you tried poweroff instead of shutdown -h now, might work.

I just tried it. Same thing. I have tried

Code:

# shutdown -h now

Code:

# halt

and now

Code:

# poweroff

None work.

And the GUI ways to shutdown using cinnamon icons. All cause a reboot.

I would like to not have to issue a command line command to shutdown, but be able to shutdown with GUI AND with command line as a normal machine could do. I don't mind adding a script to something like /etc/rc0.d to make that happen, I just haven't found anything that works more than once.

Kindly,
Nathan
