Boot hangs at "loading initial ramdisk" when SAS drive attached?

I’ll admit, I’m not entirely sure where to best go for help at this point. I’ve got other issues with the SAS disk, but pursuing things on the SAS side hasn’t been fruitful, and I’m kind of hoping fixing the boot issue will get multiple birds with one stone. (If nothing else, the most annoying one…)

Title gives the gist of it. Sometimes I’ll get lucky and the OS will boot after a longer wait than usual - the LTS kernal seems to have better luck than the Zen one. Confirmed it was something to do with the SAS drive after I unplugged the drive, leaving everything else in. Heck, I plugged a SATA drive into the same slot - otherwise identical setup - and not only does the boot not hang, but the SATA drive appears to be working just fine.

SAS drive is a 10 TB, 12 Gb/s, 7.2k HGST (HUH721010AL5204). Card is a SAS2308 9207-8i. Oddly, it had 8e firmware installed when it arrived (I’ve confirmed it’s an 8i - the ports are internal). I’ve managed to flash the card to IT mode with the latest, correct firmware and remove the BIOS - that said, while sas2flash reports the right board + product ID now…

…it still shows as an 8e in the system info for some reason.

02:00.0 Serial Attached SCSI controller: Broadcom / LSI SAS2308 PCI-Express Fusion-MPT SAS-2 (rev 05)
	Subsystem: Broadcom / LSI 9207-8e SAS2.1 HBA
	Kernel driver in use: mpt3sas
	Kernel modules: mpt3sas

I’ll admit, I’m slightly worried that might have something to do with my issues. I’m thinking of switching for a SAS3008 card, anyhow (if nothing else, I realized it actually supports 12 Gb/s), but I’m a little worried I’ll still have the same issue.

System is fully up-to-date as of ~30 mins ago.

Any suggestions on what to try?
