=========== qemu tests:
Crashes:
Various crashes in pl011_probe() due to commit f2d3b9a46e0e ("ARM: 9220/1: amba: Remove deferred device addition"). The suggested fix is at https://lore.kernel.org/lkml/20220811190747.797081-1-isaacmanjarres@google.com/T/ and mostly works but exposes or introduces another crash. The suggested fix for that crash introduces yet another crash. See https://lore.kernel.org/lkml/20220811195234.GA4018948@roeck-us.net/T/#m2192446c13d46612a00c4d499da7896d692db75c for details.
Update: The final patch to fix this problem has been submitted. I'll need to look it up.

Various imx emulations hang in scsi_remove_host() during reboot when booting from usb. Bisect points to the patch series at https://lore.kernel.org/all/20220712221936.1199196-1-bvanassche@acm.org/
