Kernel Panics 2019 iMac Pro with Pegaus R4i

My 2019 iMac Pro started crashing and I'm not really sure what caused it. It has a 32TB Pegaus r4i installed upon purchase but nothing new has been added since. Can anyone assist with deciphering the attached crash log? (File was too large so I added a link to it.) Panic Log


Thanks!

1) I can't see the Panic log in the link that you posted.

2) Panic logs generally only reveal clues and not the cause.

3) Kernel Panics can come from hardware and/or bad software.


The fastest and easiest way to track down hardware and software issues, is using EtreCheckPro.


Download and run the free version of EtreCheckPro, from > https://etrecheck.com/en/index.html

You can attach the log by using the "Additional Text" icon which looks like a piece of paper on the forum editing toolbar. It is always best to utilize the forum's tools so that the uploaded items remain accessible years later so that others may be better able to understand & learn from the thread.


Plus when posting Kernel Panic logs, it is best to post several if they are available so that we can see if there is any pattern to them. The EtreCheck report will show summaries of the Kernel Panic logs (sometimes it contains enough information, other times it doesn't include any relevant information since these logs can take a lot of different forms).

In most recent MacOS versions, the previously built-in Drivers for Promise devices (also invoked and used by several other devices) were deprecated because they violated to increasingly grueling standards for MacOS extensions. The built-in extensions are now a very old version.


Readers have been forced to side-load different versions of additional extensions to get their Promise devices to operate.


Be sure to check with Promise and obtain the absolute most up-to-date Drivers, and any additional device they may offer.
