More than two NVME's on HighPoint SSD7505?

[jas]

Hi. I have had great success with two NVME's in a HighPoint SSD7505 for a production system for months.  I'm building a second machine and wanted to populate all four NVME slots, but I got kernel messages on boot.  I have tried both 4 NVME's and 3 NVME's and tried a couple of different NVME's in case it was a NVME problem rather than a problem with the HighPoint device.

See links below for photos of kernel output (the forum says the upload folder is full so I can't attach them here):

I'm using Trisquel aramo with Linux-libre kernel 5.15 and 6, both relatively recently upgraded.  At this point the boot seems to hang even though the kernel continues to print things when I shut down the machine.  When I remove the two last NVME's and only have two NVME devices in the card, the boot works fine and everything has been stable for some time already.

This is a Talos II Lite system, and the HighPoint SSD7505 is in the only PCI slot that fits.

Any ideas?

Are there settings on the HighPoint you can change? Or it might need a firmware update?
