Andy do you have any ideas how to disable "i915 fast suspend/resume" ?
Try i915.fastboot=0, I think. Although that seems to be the default,
so I may be off-base here.
You could also try intel_iommu=on and/or intel_iommu=off -- there are
historical issues there.
TBH, though, given the luks involvement, this could be some nasty
plymouth interaction. Fiddling with quiet and rhgb could help.
Also, booting with no_console_suspend might give a better error message.
