Does anyone experience issues with I/O intensive operations using btrfs and BFQ io scheduler? I had a kernel panic while running (almost at the start) a scrub and I glimpsed the elevator.c filename on the kernel dump before I had to hard-reset. If this is not the place to ask because maybe BFQ or ck patchset is not supported under this list please let me know and I will redirect the question elsewhere. Otherwise I can provide all informations to reproduce it - it was reproducable. Regards, Leonidas --
