The 2D driver for Xorg works fine, the 5.3-RELEASE AGP and radeondrm drivers load OK, but running an OpenGL program fails with an error in radeon_cp_cmdbuf (from syslog): error: [drm:pid564:radeon_cp_cmdbuf] *ERROR* bad cmd_type 0 at 0x560008 I've been looking at the source, and IMHO (not a kernel guru) it might be a 64 bit issue. The radeon_cp_cmdbuf function contains a switch statement that evaluates an integer argument copied from user space via fuword(9), which returns a long value. Since long is 64 bits, and int is 32 bits on AMD64 this might cause trouble? For completeness, my system has an MSI Neo FSR motherboard with a KT8T800 chipset. Roland --=20 R.F.
