Sorry for the late reply, I've been out of the country and just returned home.

I installed that and rebooted with kernel boot options: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" The bug was still present on kernel 6.12.32-amd64, none of my SAS drives attached via my LSI card were coming up. I edited the boot options to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=realloc=off" And that appears to have fixed it. My SAS drives are now showing up and I can interact with them as normal. Thanks for the tip, lord2y!
