Description Joakim 2014-05-04 12:22:07 UTC 
On 2 different systems, trying to update openvz-sources from 2.6.32.84.26 to 2.6.32.88.4, after emerging the new kernel, copied the old config to new /usr/srs/linux/ and running

# make oldconfig

in that dir, using same values for new settings as in the conf file offered on openvz site, I get this error:

Exactly same error happens with sys-kernel/openvz-sources-2.6.32.90.2
Comment 2 Joakim 2014-06-03 12:09:01 UTC 
As I appear to be alone with this I concluded it most likely has to be a configuration problem and after some hours of comparison of .config files I was able to solve it by changing

CONFIG_LEDS_CLASS=m

to

CONFIG_LEDS_CLASS=y

Although that leads to another problem with building modules I am closing this as that is another problem and may also be caused by configuration.
