In summary, these are the ones that hit: check_4k_alignment() KEY_OFFSET(&w->key) is not 4KB aligned check_4k_alignment() KEY_OFFSET(l) + KEY_SIZE(r) is not 4KB aligned check_4k_alignment() KEY_START(k) is not 4KB aligned The whole dmesg output that we have is here: https://pastebin.com/nuYFi66K And some of the traces separated by error message are shown below. The ones below have a unique backtrace, but they may not cover all unique backtraces. ==================================================================== Of those that hit, These are the ones that were accompanied by SCSI errors: [54947.892574] bcache: check_4k_alignment() KEY_OFFSET(&w->key) is not 4KB aligned: 15724561783 [54947.893173] CPU: 5 PID: 1166 Comm: bcache_writebac Tainted: G O 4.1.49-5.el7.x86_64 #1 [54947.893757] Hardware name: Supermicro X9SCL/X9SCM/X9SCL/X9SCM, BIOS 2.10 01/09/2014 [54947.894323] 0000000000000286 8c136ca15cff4205 ffff8807ebea3d58 ffffffff816ff534 [54947.894907] ffff88080a7b6aa0 ffff88080a7b0000 ffff8807ebea3d68 ffffffffa05beb63 [54947.895515] ffff8807ebea3e08 ffffffffa05be174 00000003a93e4e90 ffff8807ef36c4c0 [54947.896132] Call Trace: [54947.896705] [<ffffffff816ff534>] dump_stack+0x63/0x81 [54947.897285] [<ffffffffa05beb63>] check_4k_alignment.part.9+0x24/0x26 [bcache] [54947.897853] [<ffffffffa05be174>] read_dirty+0x444/0x4a0 [bcache] [54947.898418] [<ffffffffa05be1d0>] ?
