Subject: build failure; CONFIG_HZ* unset if power management is not selected (2.6.12-rc5-mm1)
Date: Sat, 28 May 2005 00:05:48 +0200 (CEST) [thread overview]
Message-ID: <Pine.LNX.4.62.0505280000020.2370@dragon.hyggekrogen.localhost> (raw)
I just did a "make randconfig" in 2.6.12-rc5-mm1 to see if it would turn
up some unexpected failures - and indeed it did. The randomly generated
config didn't set CONFIG_PM and that in turn resulted in none of
CONFIG_HZ, CONFIG_HZ_100, CONFIG_HZ_250 or CONFIG_HZ_1000 being set
either. This resultes in the following spectacular build failure :
