Dear Linux AMD folks, There is a regression introduced by a commit after Linux 4.17-rc4 causing the X.Org X server start to fail with the Radeon module loaded on Debian Sid/unstable. The same Linux kernel build works with the modesetting driver on the same system (no module *radeon* loaded) and with i915 and the modesetting driver on a different system with Debian 9.4 (Stretch/stable). > [ 16.263] xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) > [â?¦] > [ 16.765] (EE) 0: /usr/lib/xorg/Xorg (xorg_backtrace+0x50) [0x5b4e60] > [ 16.766] (EE) 1: /usr/lib/xorg/Xorg (0x40d000+0x1abd92) [0x5b8d92] > [ 16.766] (EE) 2: linux-gate.so.1 (__kernel_rt_sigreturn+0x0) [0xb7f2ad5c] > [ 16.766] (EE) 3: /lib/i386-linux-gnu/libc.so.6 (0xb78a0000+0x140099) [0xb79e0099] > [ 16.766] (EE) 4: /usr/lib/i386-linux-gnu/dri/r600_dri.so (0xb62f9000+0x6698fd) [0xb69628fd] > [ 16.766] (EE) 5: /usr/lib/i386-linux-gnu/dri/r600_dri.so (0xb62f9000+0x43a7a8) [0xb67337a8] > [ 16.766] (EE) 6: /usr/lib/i386-linux-gnu/dri/r600_dri.so (0xb62f9000+0x66eab3) [0xb6967ab3] > [ 16.766] (EE) 7: /usr/lib/i386-linux-gnu/dri/r600_dri.so (0xb62f9000+0x66ee41) [0xb6967e41] > [ 16.767] (EE) 8: /usr/lib/i386-linux-gnu/dri/r600_dri.so (radeon_drm_winsys_create+0x902) [0xb6ab7942] > [ 16.767] (EE) 9: /usr/lib/i386-linux-gnu/dri/r600_dri.so (0xb62f9000+0x32e73) [0xb632be73] > [ 16.767] (EE) 10: /usr/lib/i386-linux-gnu/dri/r600_dri.so (0xb62f9000+0x50093e) [0xb67f993e] > [ 16.767] (EE) 11: /usr/lib/i386-linux-gnu/dri/r600_dri.so (0xb62f9000+0x3bcba3) [0xb66b5ba3] > [ 16.767] (EE) 12: /usr/lib/i386-linux-gnu/dri/r600_dri.so (0xb62f9000+0x3b7ef8) [0xb66b0ef8] > [ 16.767] (EE) 13: /usr/lib/i386-linux-gnu/libgbm.so.1 (0xb7236000+0x3ef5) [0xb7239ef5] > [ 16.767] (EE) 14: /usr/lib/i386-linux-gnu/libgbm.so.1 (0xb7236000+0x4230) [0xb723a230] > [ 16.767] (EE) 15: /usr/lib/i386-linux-gnu/libgbm.so.1 (gbm_create_device+0x58) [0xb7237cd8] > [ 16.768] (EE) 16: /usr/lib/xorg/modules/libglamoregl.so (glamor_egl_init+0x84) [0xb725ab04] > [ 16.768] (EE) 17: /usr/lib/xorg/modules/drivers/radeon_drv.so (0xb72e2000+0x52fef) [0xb7334fef] > [ 16.768] (EE) 18: /usr/lib/xorg/modules/drivers/radeon_drv.so (0xb72e2000+0x44b14) [0xb7326b14] > [ 16.768] (EE) 19: /usr/lib/xorg/Xorg (InitOutput+0xab7) [0x48e677] > [ 16.768] (EE) 20: /usr/lib/xorg/Xorg (0x40d000+0x3db81) [0x44ab81] > [ 16.768] (EE) 21: /usr/lib/xorg/Xorg (0x40d000+0x2723a) [0x43423a] > [ 16.769] (EE) 22: /lib/i386-linux-gnu/libc.so.6 (__libc_start_main+0xf1) [0xb78b8e81] > [ 16.769] (EE) 23: /usr/lib/xorg/Xorg (0x40d000+0x27278) [0x434278] There is no error message in Linux.
