Guys, i really need urgent help with this.. More info:

P410 controller, disks are non-HP, upgrade was from 4.2016->10.2016 SPP. OS - ESXi 5.5u3

Is there any way to roll back the upgrade?

The issue is possibly not with SPP since you installed the latest, but you need to update ESXi with the the one from HP for 5.5U3b that was put out in December it should have the driver rollups that were put out in the offline bundle for HP with ILO fixes 2.60xxx

The way I deployed it was pulling it from vmware look for:   VMware-ESXi-5.5.0-Update3-3568722-HPE-550.9.6.5.9-Dec2016.iso

I deployed it with an update baseline using VUM (Virtual Update Manager)

Hope that helps..good luck!
