22:28:40 <jayjwa> I just tried to update to r151054 and got a hung system on boot: No SOF interrupts have been received, this USB OHCI hostcontroller... does anyone know why/what this is?
22:30:14 <jayjwa> Followed https://omnios.org/upgrade
22:48:13 <tsoome_> jayjwa for some reason your usb does not want to play along, it is a bit interesting. Did you try cold start?
22:49:24 <jayjwa> Rebooted via reset, previous version 052 works. I'll try a full reboot.
22:52:18 <jayjwa> That worked. Whoa, scary stuff. 
22:52:43 <jayjwa> So, reboot to previous worked but update required an actual power-off. 
22:53:46 <tsoome_> meaning, the reboot left usb controller into some state the driver startup was unable to handle. 
22:54:36 <tsoome_> or, rather, state which is not handled by driver startup...
22:55:06 <jayjwa> I'll have to remember that going forward. 
22:56:03 <tsoome_> I havent seen this myself often, but after a while this message has been pop up sometimes.
22:56:24 <tsoome_> likely hardware specific.
22:58:19 <jayjwa> It's a good idea to delete old boot environments, yes?
22:58:39 <jayjwa> Just keep current and last known good...
22:58:52 <tsoome_> once you are very sure you do not need anything from those or new one is stable enough for your needs
22:59:34 <tsoome_> usually 1-2 is good idea to keep from regular updates
