Subject: bcache oops in bch_insert_data with the latest stables fixes (3.10.15)
Date: Sun, 06 Oct 2013 12:38:53 +0200	[thread overview]
Message-ID: <52513DBD.80005@excellency.fr> (raw)

Hello,

I get the following oops immediately after booting on 3.10.15. 
Everything works fine in 3.10.10. Both the backing and cache devices are 
on top of mdadm.
