I have a related reproduction on another AMD Picasso/Raven2 system. Hardware:
* HP 15s-eq0003nv * Product: 8RU92EA * Board ID: 86FD * AMD Ryzen 5 3500U * Radeon Vega / Picasso / Raven2 * Kubuntu * Kernels 7.0.0-30 and 7.0.0-31 * BIOS F.79, released 2026-04-16 My failed normal boot also reports: "amdgpu 0000:04:00.0: psp gfx command LOAD_TA(0x1) failed and response status is (0x7)" It also reports: "RDRAND is not reliable on this platform; disabling." However, in my case AMDGPU continues initializing successfully afterward. The eventual failure is during the DRM/compositor handoff. The failed boot showed: simpledrm initialized on DRM minor 0 then: amdgpu initialized on DRM minor 1 KWin subsequently reported: "Atomic modeset test failed! No such device" "Failed to open drm device /dev/dri/renderD128" "Primary gpu has been removed! Quitting..." I found that the decisive workaround was: initcall_blacklist=simpledrm_platform_driver_init without nomodeset. That fixed normal graphics boot. After applying it permanently in GRUB, the machine now boots normally on kernel 7.0.0-31. I am posting this because the PSP LOAD_TA(0x1) error on my Picasso/Raven2 system appears alongside the simpledrm/amdgpu handoff failure. I don't know whether the two issues are causally related, but the combination may be useful when comparing affected systems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2102188 Title: amdgpu: Secure display: Generic Failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amdgpu/+bug/2102188/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
