I'm not sure how much that helps, but I can't reproduce any of this on my X2 (which is quite closely related to the U2/U3). I'm only encountering non-working reboot when applying Marek's latest IOMMU runpm patchset. > The failure seems to be present for long time, at least since v4.2.

IIRC then pwrseq only plays a role for booting from eMMC. > ext4 backtrace present in your OOPs might be related to improper reboot. > Even for emergency reboot you should first sync, then remount ro and > finally reboot (so sysrq: sub). I currently don't have access to my UART adapater, but I'll try to reproduce the Oops by issuing a reboot SysRq directly.
