Title:
Kernel does not detect alr
I'm using 14.04.3 on Dell XPS 13. I just updated the kernal to 3.19 as
recommended on Dell's forum to try and solve my issue with the wifi not
turning on after suspend. I didn't have any boot issues with the
connected USBs (yet) but I did noticed an issue after returning from
suspend. Hope this hel
I cannot speak for the bug opener, but for me this bug has been resolved
(or it resolved itself otherwise, don't know). So you can safely ignore
my previous post from now. :)

Hi,
I freshly installed 15.04 about a week ago (my kernel is
19.0-22-generic) and am experiencing similiar behaviour, with some
additional symptoms to those described already:
- When the problem occurs for me, startup time spent on the loading screen
("colored dots") goes up from less than a sec
I happened again after rebooting the first time into the 3.19.0-14
kernel yesterday. So it is not solved yet.

Title:
Kernel does no
I am currently running on 3.19.3 upstream and the bug did not occur. But
I have to point out that the bug only occurred sometimes with the latest
Ubuntu vivid kernel. I do not know yet how to reliably trigger this bug,
it seems it needs some special conditions to happen.

Can you also test the latest 3.19 upstream stable kernel? This will tell
us if the fix in 4.0-rc5 was also sent for inclusion in the stable
releases. It can be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19.3-vivid/

The issue first happened after upgrading to vivid from utopic. The
utopic kernel did not show this behaviour.
I did a short test with the upstream kernel and the issue could not be
reproduced with it. Booting back into the Ubuntu kernel 3.19.0-9 on the
other hand exhibited this issue again.
** Ch
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.0 kernel[0
