I've uploaded a patch against 2.6.21-rc4 to http://tglx.de/private/tglx/2.6.21-rc4-trace/2.6.21-rc4-trace.patch.bz2 It contains all changes in Linus tree since -rc4 plus the two pending fixes (http://tglx.de/private/tglx/2.6.21-rc4-pending/) along with a backport of the latency tracer from the realtime preemption patch. Can you please apply the patch on top of -rc4 and build it with the configuration, which exposes this strange behaviour. Please enable also CONFIG_LATENCY_TRACE in the Kernel hacking menu. When the problem is visible, then run trace-it (http://tglx.de/private/tglx/2.6.21-rc4-trace/trace-it.c) as root: # trace-it >trace.txt This captures roughly one second of kernel code pathes. Please stick trace.txt into Bugzilla.
