Comment 3 collura 2013-10-05 06:20:53 UTC
problem still exists on the fc20-alpha livecd

Comment 4 collura 2013-12-01 12:42:26 UTC
fc20 beta system having problem booting some kernels after 3.10.x.fc19 (from 3.11.x.fc20 to 3.13.0-0.rc1.git0.1.fc21) so this bug stays open for now, 
but 3.13.0-0.rc1.git1.1.fc21 and 3.13.0-0.rc2.git0.1.fc21 have working brightness sliders so there is some progress. :')

Comment 5 collura 2013-12-17 07:02:34 UTC
no brightness slider freezes as of:

  kernel-3.12.5-300.fc20.x86_64

  kernel-3.13.0-0.rc4.git0.1-fc21.x86_64

closing as errata.

thanks.
