I have been getting panics consistently after doing a btrfs replace operation on a raid1 and rebooting. I linked a photo of the panic; I haven't been able to get a text capture of it. https://ibin.co/2vx0HhDeViu3.jpg I'm getting this error on the latest 4.4, 4.1, and even on an old 3.18.26 kernel I had lying around. I tried the remove root_log_ctx from ctx list before btrfs_sync_log returns patch on 4.1 and that did not solve my problem either. I'm able to boot into single-user mode and if I don't start any processes the system seems fairly stable. I am also able to start a btrfs balance and run that for several hours without issue. If I start launching services the system will tend to panic, though how many processes I can launch will vary. I don't think that it is a particular file being accessed that is triggering the issue since the point where it fails varies. I suspect it may be load-related. Mounting with compress=no doesn't seem to help either. Granted, I see lzo_decompress in the backtrace and that is probably a read operation. Any suggestions? Google hasn't been helpful on this one...
