Mac Pro 2013 / macOS Big Sur 11.3 / Promise Pegasus2 R4
After upgrading to macOS Big Sur 11.3 I am notified that the two volumes on my Promise RAID are disconnected when my Mac wakes from sleep.
Console log shows the Mac thinks the cable has been disconnected - it hasn't and same cable was working fine with macOS 11.2.3

I also tried a new Thunderbolt 2 cable - same issue.
Anyone else seeing this behaviour?
Update - 29th Oct 2021
I raised a support ticket when I became aware of this issue (Case #20210511022143S, in case anyone wants to reference it in any communication with Promise) but sadly seem to be getting nowhere with Promise Support about this.
The last response gave the impression that they had not read and understood the original reason for the ticket and many updates added with each macOS system update that did not fix the issue from Apple's side.
They even suggested that I remove the Promise Driver - something that is not possible as the driver is supplied by Apple and resides on a sealed (read only) System Volume on Big Sur and Monterey.
I think I am getting to the point of retiring this unit which is a real shame as it has performed flawlessly till this issue came about as a result of some change Apple made with the 11.3 update.
