A quick update here. After running the test on the following build, the symptom still can be observed. If test config configured as RAID mode, the system can not find any disk. Moreover, after rolling back the change (RAID -> AHCI), the system ran the recovery process instead of booting into the desktop.
# Steps to reproduce: 1. Select "AHCI" mode in BIOS (Boot to BIOS, "Devices" => "Configure SATA as" : AHCI) 2. Boot up the system 3. Reboot the system and then enter the BIOS 4. Change the to "RAID" 5. Save the config and then boot up the system 6. Check if the system can boot to the desktop # Expected result: The system can boot to the Desktop # Actual result: The system froze during startup # Build info: - Kernel version: 5.6.0.1020 (5.6.0-1020.20ubuntu1.lp1888311 ): Failed - Kernel version: 5.6.0.1021 (focal-amd64-X00-20200821-272.iso): Failed - Kernel version: 5.6.0.1028 (5e125d13371b3049d238a4bf5f2108bfbfe8a900): Failed # Test config: P340 (P340-SIT-C1) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.6 in Ubuntu. https://bugs.launchpad.net/bugs/1892288 Title: Comet Lake PCH-H RAID not support on Ubuntu20.04 Status in HWE Next: New Status in OEM Priority Project: New Status in linux package in Ubuntu: Invalid Status in linux-oem-5.6 package in Ubuntu: Invalid Status in linux source package in Focal: Fix Committed Status in linux-oem-5.6 source package in Focal: Fix Committed Bug description: [Impact] Add Intel Comet Lake PCH-H PCI ID to the list of supported controllers.
