My new laptop is taking very long (a few minutes) until it reaches the log-in screen.

Here is the output of dmesg: http://pastebin.com/MuW79kVd

I think the important part is the following gap in the time:

[    6.861250] input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1b.0/sound/card1/input20

It is an HP Probook 640 laptop. Here is some more information about the hardware (I am not sure what is important here).

Any suggestions on how to fix this?

  • Does it run OK with Ubuntu 14.04 LTS? Did you add/remove any USB devices (eg. mouse), or where they present at power on? – david6 May 21 '15 at 9:46
  • I did not try an earlier version, it is a new Laptop. The devices were all plugged in from the start. I will try to restart without having the mouse plugged in later. – peq May 21 '15 at 13:17
  • Ok, so without the mouse plugged in the boot takes about 10 seconds, so at least I have this as a temporary fix. Plugging the mouse in after log-in works without problem. The message I get during booting with the mouse is "A start job is running for udev wait for complete device initialization". – peq May 21 '15 at 18:26
  • This could be a driver issue, but I have only heard of similar issues with (inbuilt) touchpads. That was related to interrupts and device conflicts, with new drivers for touch screens (so unrelated to what you have). – david6 May 21 '15 at 19:25
  • Also try a different USB port, and/or check BIOS/setup for port hibernation / power saving. – david6 May 21 '15 at 19:27

This may or may not work for you, but I had the same error you mention in a comment below your post and it was related to loading my built in bluetooth device.

A start job is running for udev wait for complete device initialization

Followed by the USB disconnect message.

After a few reboots my syslog hinted to error -110 which is power related, this error did not show up during the first reboots.

I got it working again by shutting the computer down and disconnecting the power cord for a few seconds, after that the computer booted fast again and I got the Bluetooth device back.

  • As a side note, my computer is an Intel NUC and I suspect that the issue is related to connecting a WD Elements drive to one of the USB ports. – Horselover Fat Aug 13 '15 at 18:08
