Hi Tj, all,

I can get kernel panic on my machine with kernel 3.9.0-rc7-4-gbb33db7 every time
after booting for several minutes.

Here attached the panic picture and the config.
I'm sorry that the panic log is not completed.

But fortunately, the panic was gone when I reverted the below commit from Tj,

    block: add missing block_bio_complete() tracepoint

I think this will be helpful for you to resolve this bug, and this may be urgent,
because it's already rc-7 now.


Thanks,
Wanlong Gao
