Hi Andy,
Can you share the following details?
1. Fw version in the card you have. Use below command to get the fw_version sys file.
2. Expander and drive details and how you connected it to HBA?
3. Can you enable full logs and hot plug the expander/devices and share the log if the discovery fails.
Find /sys -iname "fw_version"
Find /sys -iname logging_level
Echo oxfff > "logging_level sys file"
Also can you test with latest Linux stable release?
Thanks,
Suresh
