Finally solved an annoying problem. New mac pro 7,1 with W5700X graphics and Areca 1883-ix RAID card. Was getting frequent kernel panics on shutdown and the machine would reboot. Rock stable otherwise. Same with BS 11.3.1 and 11.3.2. Drivers UTD.
Snippet of typical Crash dump:
Seemed like a shutdown issue with the Areca RAID card. I found a blog where they had problems with a PCI/SSD card when it was in PCI slots 4 or 5. My card was in slot 4, so I moved it to 3 and problem seems resolved. Also made sure was on bus A.
Perhaps this reflects a problem with storage devices in those PCI slots.
Hope this helps others.
