So, I added these patches to my 4.4.2 kernel, but it still crashes when seeing one cache device at boot. Crash: https://goo.gl/photos/8H1DtYjSijK4ngFv6 while (!kthread_should_stop()) { try_to_freeze(); w = bch_keybuf_next(&dc->writeback_keys); if (!w) break; >>>>> BUG_ON(ptr_stale(dc->disk.c, &w->key, 0)); if (KEY_START(&w->key) != dc->last_read || I have to remove the partition for my system to boot. Before I destroy it, any other patches I should try? And to be fair, it's a huge pain to deal with this, there should be an easier way to just turn bcache off from the kernel command line. In this case it was really a lot of work to get back to even a booting system. You also said: > 4.1.18 has the patches, so unless there is something specific in 4.4 that > you need, I recommend 4.1.

Sadly, I run btrfs, I can't just go to random old kernels like this. Is bcache not stable in up to date kernels?
