Has Sequoia finally resolved the PCIE M.2 NVME mounting issues so many faced?

It looks likes some people are reporting Sequoia has resolved the bug seen by so many in Sonoma, that caused NVME and RAID cards to intermittently mount on reboot.

The details are all here: PCIE M.2 drive not mounting after Sonoma … - Apple Community

And here: https://forums.macrumors.com/threads/mac-pro-2019-nvme-raid-drives-failing-to-mount.2366297/page-25

Having spent far too long "downgrading" from Sonoma to Ventura just to get my Mac Pro 2019 working with all attached drives, I'm extremely hesitant to "upgrade" to Sequoia until it's 100% certain the bug is gone!

Mac Pro, macOS 13.6

Yes and no. Seems 15.1 fixed the issue of intermittent successful booting with Raid-assembled NVMEs on multi-M2 card (mine are Sonnet x2 and x4 cards) mounted in the backplane 7,1 PCIe buss. BUT 15.2, which I upgraded to, degrades it back. And is no longer solid. I’ve just gone through the long process of returning to 14.7 because I could not get a 15.1 image.

I'd like to know too, specifically for the MacPro 2019

which Driver are you using with it? {AppleRaid, SoftRAID, Disk Utility (plain), other}

Plain disk utility...

Ok, that's easy enough. I've sent a summary of the issue to them, but I won't hold my breath!

We now have Sequoia 15.3.1… anyone game to test whether this finally fixed Apple’s NVME mounting issues?
