Please install the kernel at
http://people.canonical.com/~cndougla/sched_trace/. Then reboot and
perform the following steps:
# echo function >/sys/kernel/debug/tracing/current_tracer
# ech0 1 >/sys/kernel/debug/tracing/options/latency-format
# echo 1 >/sys/kernel/debug/tracing/tracing_enabled
Then do whatever you need to trigger the issue. Once the bug has been
triggered, do:
# cat /sys/kernel/debug/tracing/trace | bzip2 >/tmp/trace.bz2
Finally, attach the trace.bz2 file to this bug so we can take a look.
Thanks
