> After upgrading from Debian Bookworm to Trixie, and subsequently to kernel linux-image-6.12.27-amd64 (version 6.12.27-1), my LSI SAS2008 HBA is no longer being initialized correctly, preventing access to the attached SAS drives. This appears to be a regression, as the LSI SAS2008 HBA and attached SAS drives work perfectly under kernel 6.1.0-37-amd64. The SAS drives connected to the LSI HBA are not detected by the system (do not appear in lsblk). The mpt3sas driver loads but fails to initialize the card. lspci -nnk for device 04:00.0 shows Kernel modules: mpt3sas but does not show a "Kernel driver in use" line when the failure occurs.

Can you try booting 6.12.27-amd64 passing the kernel boot option pci=realloc=off?

Hope this helps.

Best,
A.
