[CentOS] no video with Aspeed (ast module) and latest kernel
Hello, I have a CentOS Stream 9 server. It is an Intel D50DNP1SBB one with: 02:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 52) (prog-if 00 [VGA controller]) DeviceName: ASPEED AST2600 Subsystem: ASPEED Technology, Inc. ASPEED Graphics Family Flags: medium devsel, IRQ 16, NUMA node 0, IOMMU group 42 Memory at 94000000 (32-bit, non-prefetchable) [size=16M] Memory at 95000000 (32-bit, non-prefetchable) [size=256K] I/O ports at 1000 [size=128] Capabilities: [40] Power Management version 3 Capabilities: [50] MSI: Enable- Count=1/4 Maskable- 64bit+ Kernel driver in use: ast Kernel modules: ast Under kernel 5.14.0-386.el9.x86_64 I'm able to connect via bmc without any problem both in text mode (multi-user.target) and graphical (graphical.target). Both with and without Wayland enabled in /etc/gdm/custom.conf This morning I updated the system and the kernel is now 5.14.0-404.el9.x86_64, and I'm not able to see the console in any of the 3 configurations above in my bmc kvm remote terminal. Ssh connection to the system is ok without problem. Inside the remote kvm console I see the grub menu, I see the scrolling kernel boot sequence (I removed rhgb quiet options), but at the end my remote kvm display square disappears. How can I debug? Can I disable DRM for the ast kernel module? or start with vesa in any way? screenshot with 5.14.0-386.el9.x86_6: https://drive.google.com/file/d/1VoDYAYLOIrErOGVNXgR8wNypzxyjd7k8/view?usp=sharing screenshot with 5.14.0-404.el9.x86_64: https://drive.google.com/file/d/1UClBOXHIjxc4rqiKW0wbMwIYKlrB_kGn/view?usp=sharing Thanks in advance, Gianluca
