Build Identifier: 

Starting with kernel system would not finish booting...the screen display the login prompt (right before it would normally go to the full screen user login page), and continusouly blink...after pressing enter key, this message is displayed and the screen continues to blink:
logitech-hidpp-device 0003:046D:200D.0006 Unable to retrieve the name of the device.

It seems that the system is not reading the device name correctly because 200D is not a valid logitech device.  Here is the lusb output when I boot back with

What more information do you need?

Reproducible: Always

Steps to Reproduce:
1. I presume it's the kernel level... works OK...Anytime I install updates that include a kernel update, it breaks.  So, and I have tried and they all fail with the same error conditions.  I recover by rolling back to

Actual Results:  
boot does not complete. at tty login, screen just blinks continuously and outputs the logitech error whenever enter key pressed.

Expected Results:

Kernel did not resolve the problem.
Comment 2 Jiri Slaby 2018-02-13 11:36:37 UTC
I can't see anything obviously broken between 4.14.12 and 4.14.13 in this area.

Could you boot without splash-silent and quiet?

Xorg.0.log during boot

Shows segment fault in X near end of log.
Comment 4 Richard Pace 2018-05-11 16:28:17 UTC
From just looking at the journald log I mistakenly viewed this as a usbhid problem.  But now looking at the Xorg.0.log I can see a segment fault.  Xorg.0.log attached from attempt to boot with the latest kernel 4.16.6-1-default.

Same symptoms as when first reported with 4.14.13-1 kernel. 

Reverting back to 4.14.12-1 i see that the X server is version 1.19.5, and the X server version that now fails with the segmentation fault is 1.19.6.  Not sure when 1.19.6 was introduced, but I suspect 4.14.13-1 was using 1.19.6.

Any chance you could look at this again with the additional documentation?
Comment 9 Takashi Iwai 2018-05-27 05:54:50 UTC
Does your system have Mesa-dri package installed?
Comment 10 Jiri Slaby 2018-06-16 12:30:26 UTC
Closing due to lack of response.
