The "timeout sending FIS" is the real problem.
This is done in polling mode so is probably not an interrupt issue.
Probably something changed in the AHCI controller setup by the BIOS, or
some hardware protection (e.g. iommu) has been activated which prevents
read/write to the controller.
Could you check if the new bios has options to tune in this area ?
