Hello Linus,
On the system on which bug #32982 has been triggered md0, md1 and md2 have been configured as two-disk RAID1 (mirroring).
I've done my best to trigger enough I/O in order to obtain reliable bisect results. A difficulty I encountered during bisecting though was that I encountered unbootable kernels (all skipped revisions).
