Koba and I got together to discuss and investigate the issue within this week and last week. It seems to us that there is something wrong with the OEM build because the issue can still be observed on OEM build after upgrading the Kernel to 5.6.0.1029. Details are as follows.
# Stock Ubuntu & 5.6.0.1030-oem - Test result: Issue cannot be observed. After configuring as RAID mode, the system can boot into the desktop # OEM build (amd64-X00-20200821-272) & 5.6.0.1030-oem - Test result: Issue still can be observed. After configuring as RAID mode, the system cannot boot into the desktop. -- 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 Released Bug description: [Impact] Add Intel Comet Lake PCH-H PCI ID to the list of supported controllers.
