Created attachment 571398 [details] File: backtrace
Can this be retested on a kernel with lock usage statistics enabled, ie. CONFIG_LOCK_STAT?
that kernel did have that option enabled.
(In reply to comment #1) > Created attachment 571398 [details] > File: backtrace From the trace file I can only say that it is spinning. It does not tell me what process is holding the spinlock. Can you provide more trace info?
That information can be obtained by "echo t > /proc/sysrq-trigger", and then attach output of dmesg command here.
