btrfs scrub under linux with ck-patchset - oops

Hi list,

Before I give all the information to this email and then find that's not the right place to do so..

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

You may want to check the BFQ list, specifically [1]. It seems to be a bug in BFQ itself and unrelated to btrfs.
