I'll see if I can reproduce it. Well, just for kicks, I setup bcache with a regular disk as the backing device. Everything seemed to go ok...I was able to create an ext4 filesystem on it and mount it. I remembered I had forgotten to attach the cache, so I attached the cache, and tried copying an ISO to the mounted fs, and it immediately crashed. I was doing this remotely, and now I can't get to the box. So I'm not certain this is the full traceback, but it's what I got before I lost connection: kernel:[50655.044130] ------------[ cut here ]------------ Message from syslogd@zapazoid at Dec 17 07:39:06 ... kernel:[50655.048019] invalid opcode: 0000 [#1] SMP Message from syslogd@zapazoid at Dec 17 07:39:06 ... kernel:[50655.048019] Process kworker/5:0 (pid: 5699, ti=c78c2000 task=f27db5f0 task.ti=c78c2000) Message from syslogd@zapazoid at Dec 17 07:39:06 ... kernel:[50655.048019] Stack: Message from syslogd@zapazoid at Dec 17 07:39:06 ... kernel:[50655.048019] Call Trace: Message from syslogd@zapazoid at Dec 17 07:39:06 ... kernel:[50655.048019] Code: 8b 87 88 03 00 00 85 c0 74 17 8b 00 85 c0 74 11 8b 48 28 85 c9 74 0a 89 f2 89 f8 ff d1 85 c0 75 6b 66 83 be 84 00 00 00 00 75 04 <0f> 0b eb fe 8b 9e 90 00 00 00 85 db 75 1d ba 20 00 00 00 89 f8 Message from syslogd@zapazoid at Dec 17 07:39:06 ... kernel:[50655.048019] EIP: [<f8c759de>] scsi_setup_fs_cmnd+0x3f/0xa4 [scsi_mod] SS:ESP 0068:c78c3ed0 This box has a Phenom II X6 (1035T??).
