There are a bunch of fixes (performance, mostly) that went into mpt(7d) after snv_125 closed. There have also been a bunch of changes in the fast reboot area since snv_125.
Great! Is there anything specific to 6894775, though? It seems like performance improvements might make things worse because they could increase the load on the disks and the controller, and I suspect that the true culprit from what I've read here is likely the controller. Would the reboot changes make it likely that a reboot after 6894775 would actually work rather than just hang?
You are doing yourself a disservice by not running a newer build.
Indeed. But we SPARC orphans have had a variety of problems that have taken until b134 to resolve (not that I'm complaining; the support on these lists has been nothing short of incredible), so moving forward from b125 hasn't been an option until recently. We'll do some stress testing on a b134 test system and report back here if anything interesting results. From your perspective, what settings of zfs:zfs_vdev_max_pending and zfs_scrub_limit would be best to provide meaningful results?
