Neil, Jens? (converted top-posting into bottom-posting) Hello Linus, On the system on which bug #32982 has been triggered md0, md1 and md2 have been configured as two-disk RAID1 (mirroring).

A difficulty I encountered during bisecting though was that I encountered unbootable kernels (all skipped revisions).
