Only a subset of disks appear. 20 disks of 70, each HBA has 35 disks attached

Hi

We're experimenting to see if Truenas scale fits in our environment, but we're running into a weird problem. Only 20 of the 70 disks appear to TrueNas Scale, it's odd as there are 2 HBAs (Dell HBA355i Adp) with 35 disks attached. All the disks appear if we run Rocky Linux 9 on the system (haven't tried other OSs). Suggestions for how to best diagnose? Thanks in advance!

System:
TrueNAS-SCALE-22.02.2.1
PowerEdge XE7440
2 Xeon 4214R
384GB ram
2 Dell HBA355i Adp
70 12TB disks (ST12000NM005G 2M)
1 PERC H730P Mini
2 480GB SSD (MZ7KH480HAHQ0D3)
2 1.92 nvme (MTFDHBE1T9TDF)

In case anyone runs into something similar - the kernel driver in anglefish is too old for these hbas to work with this many disks per hba (it might work fine with less disks) The kernel for bluefin (5.15) does work.

Backporting the driver from 5.15 looks possible, but does defeat the purpose a bit.
