Subject: RT Throtteling with PREEMT-RT on UBIFS root fs update
Date: Fri, 11 Nov 2011 10:56:53 +0100 [thread overview]
Message-ID: <201111111056.53803.tim.sander@hbm.com> (raw)
Hi
We are having a problem with a slightly patched (some platform patches,
newest stable ubifs patches) 3.0.7-rt20 kernel after updating the firmware on
the first boot we get a message:
sched: RT throttling activated
and ksoftirqd/0 taking 95% of the cpu time.
Interestingly this only happens after the ubifs root has been updated on the
first boot (and not allways). Subsequent boot problems have not been seen.
Any ideas whats causing this?
Tim
