Description Adam Jirasek 2015-01-21 21:05:59 UTC 
Hello

I updated kernel from linux-3.18.0-gentoo-rc7 (SHA1: a8d8e8babe5e05fa5d67cb2a8928970d686e9687) to linux-3.19.0-gentoo-rc4 (SHA1:42cdebd02a25d7a06f025d87f63792e450eb1621) 
and I what happens is that when I start X (I use KDE) the cursor follows mouse movement with a large delay; if I can say so it seems as if cursor is moving though honey, kind of. In addition, when I change the size of a window by draging a corner with a cursor, the update of the shape for the new window may take too long too.

I quickly compared the journalctl output and found that compared to working 
version of the kernel, the log file contains some additional lines.
Before I stat bisecting the kernel I was wondering if anyone know what might be the case.

The first extra line is

Jan 21 13:21:31 localhost kernel: snd_hda_intel 0000:00:03.0: failed to add i915 component master (-19)



and then I get warning for each CPU:
