Hi, I recently tried bcache on a vanilla 4.1.12 kernel and got those strange soft lockup issues. This happens at the system shutdown only but not every time, thus I suppose that it's related to bcache devices stopping. My setup use 3 bcache devices each using dedicated hardware devices (1 HDD and 1 SSD), cache_mode is writeback and bucket/block sizes are the default ones. I saw that a similar problem was solved in 3.17 so maybe it's a regression. Any idea how to fix that ?
