Description Shlomi Fish 2017-05-15 10:18:58 CEST

Description of problem:

New kernel 4.9.28 disables the USB mouse on startup and misses many keypresses from the USB keyboard. These are standard Microsoft USB keyboard and USB mouse and the previous 4.9.27 kernel handles them fine. I'm starting Xfce using startx.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Reboot to kernel 4.9.28.
2. Login.
3. startx.
4. Try to move the mouse.

Comment 1 Shlomi Fish 2017-05-15 11:50:57 CEST

An update: I can reproduce the problem with a vanilla 4.9.28 kernel built from source, so it seems to be an upstream regression.

Comment 2 Thomas Backlund 2017-05-15 12:10:01 CEST

Please provide dmesg from both 4.9.27 and 4.9.28 so we can compare init

also provide output of lspcidrake -v

Seems like I can also fix the problem with the keyboard by plugging it out and plugging it in again.

Can you attach the part of the log that corresponds to unplugging/replugging the keyboard

which log?

Comment 9 Thomas Backlund 2017-05-15 21:13:32 CEST

Sorry for not being specific....

When you have just booted 4.9.28 and see the problems, un-plug and re-plug the keyboard, then check dmesg output, it should show up there

Still happens with kernel 4.9.29. Here is the requested dmesg output.
