MP 1,1-5,1 Mac Pro with Open Core Monterey Crash with Motu sound card

[MurdockMan]

Can anyone have a clue about this crash that occur every time when the sound card (Motu 282MKII) connected by Firewire is shutdown.

It works perfectly, just give this log and the screen's (have two) turn red and black, after 3 seconds they lose signal and come on again perfectly fine.

Se in attach the log...

🧐😫

Thank's

When I use Target Disk Mode over FireWire, my cMP locks up when the targeted device (a MBP) is powered down. This happens when I'm booted via OCLP. It does not happen with direct-booted macOS versions. I've yet to find a workaround other than shut down my cMP manually before shutting down the FW connection.

Unfortunately, a 4,1 or 5,1 needs OCLP to boot Monterey (your OS, from the log). Big Sur can be direct booted after installation with OCLP. But Monterey and later require OCLP just to boot. It seems macOS is fine dismounting devices over FireWire, but OCLP is glitching up the process. I'd be interested too if anyone knows a solution.
