[fedora-arm] State of RocPro64 support?

Some time ago I bought Rockpro64 board from Pine64. To check how EBBR works, how PCIe works on SBCs, Mali Panfrost driver etc. Board arrived yesterday. I connected serial cable (CB2102 dongles suxx, FT2232HL works fine at 1.5Mbps serial), Ethernet, HDMI and booted. Boot fails each time at same place (whole boot log attached): [ 29.043106] panfrost ff9a0000.gpu: clock rate = 500000000 [ 29.053073] rockchip-vop ff8f0000.vop: Adding to iommu group 1 [ 29.058099] panfrost ff9a0000.gpu: mali-t860 id 0x860 major 0x2 minor 0x0 status 0x0 [ 29.058948] panfrost ff9a0000.gpu: features: 00000000,100e77bf, issues: 00000000,24040400 [ 29.059820] panfrost ff9a0000.gpu: Features: L2:0x07120206 Shader:0x00000000 Tiler:0x00000809 Mem:0x1 MMU:0x00002830 AS:0xff JS:0x7 [ 29.061053] panfrost ff9a0000.gpu: shader_present=0xf l2_present=0x1 [ 29.063559] rockchip-vop ff900000.vop: Adding to iommu group 2 [ 29.147966] panfrost ff9a0000.gpu: devfreq_add_device: Unable to find governor for the device [ 29.151244] panfrost ff9a0000.gpu: [drm:panfrost_devfreq_init [panfrost]] *ERROR* Couldn't initialize GPU devfreq [ 29.173499] panfrost ff9a0000.gpu: Fatal error during devfreq init Same effect with F32 and it's 5.6.6 kernel and with rawhide and 5.7-rc4 one. Board boots to login when I blacklist "panfrost" driver with "rd.driver.blacklist=panfrost" kernel argument. Any suggestions what to look at? It's been a while since I did kernel debugging.
