I've started bisecting using your suggestion of that drm merge:
    $ git bisect log
    git bisect start
    # good: [89c3b37af87ec183b666d83428cb28cc421671a6] Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/ide
    git bisect good 89c3b37af87ec183b666d83428cb28cc421671a6
    # bad: [a2d635decbfa9c1e4ae15cb05b68b2559f7f827c] Merge tag 'drm-next-2019-05-09' of git://anongit.freedesktop.org/drm/drm
    git bisect bad a2d635decbfa9c1e4ae15cb05b68b2559f7f827c
    # bad: [ad2c467aa92e283e9e8009bb9eb29a5c6a2d1217] drm/i915: Update DRIVER_DATE to 20190417
    git bisect bad ad2c467aa92e283e9e8009bb9eb29a5c6a2d1217

Git told me I have nine steps after this. So at two hours per step I might
pinpoint the offending commit by Friday the 12th. If I'm lucky. (There are
other things to do than bisecting this issue.)

If you find that commit before I do, I'll be all ears.

Thanks,
