Hmm, that trace dump was cut off before it completed by a reset (probably your test timeout). Either you make the timeout longer or try the following on the kernel command line instead of 'ftrace_dump_on_cpu': ftrace_dump_on_oops=orig_cpu trace_buf_size=100K That reduces the output to the CPU which triggers the problem and with a smaller buffer.
