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: AR arch/x86/lib/lib.a LD vmlinux.o MODPOST vmlinux.o GEN .version CHK include/linux/compile.h UPD include/linux/compile.h CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 drivers/built-in.o: In function `led_trigger_set': /usr/src/linux/drivers/leds/led-triggers.c:115: undefined reference to `led_set_brightness' drivers/built-in.o: In function `led_trigger_event': /usr/src/linux/drivers/leds/led-triggers.c:227: undefined reference to `led_set_brightness' Makefile:845: recipe for target '.tmp_vmlinux1' failed make: *** [.tmp_vmlinux1] Error 1 -------- #

Exactly same error happens with sys-kernel/openvz-sources-2.6.32.90.2
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.
