Currently no support for quiesce, so system has to do a slow reboot.

It would be nice to have quiesce, but thats not the only blocker for the fast reboot. It is even not clear if it is worth to get fixed.

The other blockers I know of are nvme and qede.

We have a quiesce for nvme, and qede is on the way. nvme was quite a big change, I thought it best to separate this work on a per driver basis.

Fast reboot, is definitely worth fixing if you have a slow bios, not all distros run on a ramdisk.

I'd agree with Toomas, fast-reboot looks like a solution for a problem that doesn't exist (I'd really want a full POST after a panic, especially if it's hardware related; all other cases when reboot is needed, e.g. installing new hardware would require full power cycle as well).

OTOH, if quiesce is a part of suspend/resume process (and we likely still care about those for laptops), then it should be worth fixing.

having xhci_quiesce would help my particular case in working around https://www.illumos.org/issues/12445
