No deadlocks for me, but I've been hit by the 32MB issue. On 8-STABLE without the recent Xorg update (haven't done that yet) I usually startx right after boot, and this usually works fine. One time I had massive ZFS/git jobs running headless first and wanted to startx afterwards. X11 took quite some time to come up and although window "switching" was snappy, *moving* windows around was slow as hell, window contents were re-drawing at ~1FPS. This also seems to always happen if I stop X11 and startx it again. So I made a diff from a regular Xorg startup against the slow one: --- Xorg.0.log 2010-02-09 20:59:16.000000000 +0100 +++ Xorg.slow.log 2010-01-31 11:04:08.000000000 +0100 ... @@ -599,49 +599,22 @@ (II) RADEON(0): [drm] added 1 reserved context for kernel (II) RADEON(0): X context handle = 0x1 (II) RADEON(0): [drm] installed DRM signal handler -(II) RADEON(0): [pci] 32768 kB allocated with handle 0xed1a5000 -(II) RADEON(0): [pci] ring handle = 0xed1a5000 -(II) RADEON(0): [pci] Ring mapped at 0x802aa0000 -(II) RADEON(0): [pci] Ring contents 0x00000000 -(II) RADEON(0): [pci] ring read ptr handle = 0xed2a6000 -(II) RADEON(0): [pci] Ring read ptr mapped at 0x8006d6000 -(II) RADEON(0): [pci] Ring read ptr contents 0x00000000 -(II) RADEON(0): [pci] vertex/indirect buffers handle = 0xed2a7000 -(II) RADEON(0): [pci] Vertex/indirect buffers mapped at 0x812c00000 -(II) RADEON(0): [pci] Vertex/indirect buffers contents 0x00000000 -(II) RADEON(0): [pci] GART texture map handle = 0xed4a7000 -(II) RADEON(0): [pci] GART Texture map mapped at 0x812ea7000 -(II) RADEON(0): [drm] register handle = 0xfe8e0000 -(II) RADEON(0): [dri] Visual configs initialized +(EE) RADEON(0): [pci] Out of memory (-12) +(EE) RADEON(0): [pci] PCI failed to initialize.
