Subject: Second soft lockup regression in yesterday's sched.git merge
Date: Tue, 22 Apr 2008 23:39:35 -0700 (PDT) [thread overview]
Message-ID: <20080422.233935.37053549.davem@davemloft.net> (raw)
Two changets after the buggy cpu_clock() changes, we have:
commit 15934a37324f32e0fda633dc7984a671ea81cd75
Author: Guillaume Chazarain <guichaz@yahoo.fr>
Date: Sat Apr 19 19:44:57 2008 +0200
sched: fix rq->clock overflows detection with CONFIG_NO_HZ
When using CONFIG_NO_HZ, rq->tick_timestamp is not updated every TICK_NSEC.
We check that the number of skipped ticks matches the clock jump seen in
__update_rq_clock().
Signed-off-by: Guillaume Chazarain <guichaz@yahoo.fr>
Signed-off-by: Ingo Molnar <mingo@elte.hu>
Which also causes softlockup warnings on my Niagara systems.
Note this is with the cpu_clock() change reverted, and the
usual test case kernel build after a delay:
sleep 10m; time make -j64 >build.log 2>&1; make -j64 image
Some logs:
