Correct, the interesting entries right before the crash are missing. Can
you try to make the trace buffers smaller or wait longer before
terminating the thing?

16k buffer size per CPU should be completely sufficient. That should
give us roughly the last 100 entries per CPU.

'trace_buf_size=16k'

is the command line option for that.

Thanks,
