constant call trace in log.
Hi everybody, I'm a gentooer and not much of a kernel hacker, more of a tweaker, but I'm curious about this never-ending output in my syslog https://paste.lugons.org/show/2679/ It's been going on for weeks, the same thing over and over. What does it mean? And how do I stop it? I've turned off every debugging option in menuconfig I can find. irc #gentoo has not been much help. rgrds Max
(oops, sending to the mailing list as well this time, sorry, folks.) Hi Max, Maybe this might be fixed in a more recent kernel. Have you tried one? See here for a range of reasons why a CPU stall warning might happen: http://www.kernel.org/doc/Documentation/RCU/stallwarn.txt So the report time after the RCU grace period starts is controlled by CONFIG_RCU_CPU_STALL_TIMEOUT, which is to be found under 'Kernel hacking ---> RCU CPU stall timeout in seconds' from menuconfig. Failing that at runtime you can change the values of rcu_cpu_stall_suppress and rcu_cpu_stall_timeout in /sys/module/rcutree/parameters/. Cheers Julie
