Running top in another tty while loading X at the same time shows tha= t=20 Xorg uses 99.9% of WCPU. =20 Checking around, I found that the actual freeze was due to Xorg using the R= 300=20 microcode (commenting out the Load "glx" and Load "dri" in xorg.conf makes = X=20 work again). =20 I'm lost as to where to start debugging this as I cannot ssh,=20 Ctrl-Alt-Backspace or get a dump during that freeze. Since it causes a cras= h,=20 anything logged on the harddrive is lost (no sync done...) I tried running xorgcfg (graphic mode) to see if it would record something= =20 useful in Xorg.8.log and I have it attached. For some reason, X detects my= =20 lcd as having a max res of 1280x1024, but tries to open a display for=20 1600x1200 which only makes my screen show an "Out of Resolution" message. M= y=20 console shows a message similar to "R300 Microcode loaded". I can=20 Ctrl-Alt-Backspace out of X. I've tried both dri and dri-devel with no luck. So I resume: 1. Xorg 6.9.0 + R300 DRM + dri causes freeze 2. Disable dri+glx in Xorg.conf makes X work again (without drm) 3. xorgcfg tries to start in 1600x1200 for a screen capable of only=20 1280x1024, rendering it useless. Anyone using a R300 powered card (Radeon 9550/9600) with DRM+Xorg 6.9.0 out= =20 there? dmesg: vgapci0: <VGA-compatible display> port 0xe000-0xe0ff mem=20 0xe8000000-0xefffffff,0xfbe00000-0xfbe0ffff irq 16 at device 0.0 on pci1 drm0: <ATI Radeon AS 9600 AS> on vgapci0 info: [drm] AGP at 0xe0000000 64MB info: [drm] Initialized radeon 1.19.0 20050911 vgapci1: <VGA-compatible display> mem=20 0xf0000000-0xf7ffffff,0xfbf00000-0xfbf0ffff at device 0.1 on pci1 Thanks, Nicolas =2D-=20 =46reeBSD 7.0-CURRENT #0: Sat Jan 21 11:33:22 EST 2006 =20 root@clk01a:/usr/obj/usr/src/sys/CLK01A=20 PGP?
