Two things. SCSI_SCAN_ASYNC=y is set from xenial to bionic.
If we believe this is what is causing the race here, we can try booting d-i with a kernel parameter 'scsi_mod.scan=sync' specified. (or i can rebuild d-i with such kernel cmdline built-in if required). And check if that helps to resolve this case. I do wonder, if d-i should be taking the control of the scan itself, meaning, booting with scsi_mod.scan=none and doing `echo "- - -" > /sys/class/scsi_host/*/scan` at the appropriate stage of disk-detect. Or if we do async scan, trigger a rescan at disk-detect stage. `echo 1 > /sys/class/scsi_device/device/rescan` Will be checking the disk-detect / scsi code, to see if it does trigger scans, and if it correctly blocks on said scans to complete. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1751813 Title: Ubuntu 18.04 installer does not detect any IPR based HDD/RAID array [S822L] [ipr] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1751813/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
