    HD 3850 AGP lockup with OpenGL load

    I tried hard to make 3D acceleration work for my Powercolor HD 3850 AGP on the following system:

    Intel 865 mainboard (Gigabyte GA-8I848P-G)
    P4 2,8 GHz 512MB RAM

    I used fglrx drivers from Catalyst versions:
    8.7
    8.8
    8.10
    8.11
    8.12
    9.1betaRC2

    - on Ubuntu 8.10 kernel 2.6.27-9-generic
    - on Debian/Lenny kernel 2.6.26-1
    by building debs from the installer, plus one time direct install.
    (cleanup between installs by dpkg -r).

    everything installs OK, AGP initializes to 8x (intel_agp), DRI initializes, no real problems in Xorg.log visible except several warnings like
    ...
    (WW) AIGLX: 3D driver claims to not support visual 0x72
    ...

    now the problem is: every time I start an OpenGL app (glxglears or fgl_glxgears will do), the system freezes:
    With earlier drivers from Catalyst 8.8, fgl_glxgears runs for about 10 seconds; the more recent driver I use, the faster the freeze takes place:
    With 8.8 I can run
    "fgl_glxgears -loop 500"
    several times successfully, until system finally freezes in the 10th or so run.
    With 9.1betaRC2 the cube just slightly starts turning and the system immediately locks up.
    This somehow makes me unsure when hoping for upcoming driver releases to resolve the issue....

    I've been trying a hell lot of xorg Options and Option combinations from
    http://debian.wgdd.de/temp/fglrx_man/fglrx.4x.html
    without any noticeable change.

    With 8.12 I have pretty good speed in normal 2D apps, fast scrolling with Firefox, moving it around with several tabs open is no prob, too. System runs without trouble until any OpenGL app is started. (OK, I didn't test user switching and suspend - I had enough with the normal stuff...).

    On this same system, Catalyst 8.12 Windows XP drivers work fine, full AGP 8x speed, 3DMark06 runs to end without any errors, so I guess there's not a heat or PSU problem (510 W, by the way).

    Anybody a good idea what to try next - beside the obvious "go for nvidia"?

    TIA

    Thanks for all. Videocard have been sold

    Yes, my motherboard have this option. But this option didnt help me to power off videocard at shutdown automatically, didnt help me with tv-out, didnt help me with hangs at 8x

    tried that already, it had no effect on the problem. Somewhere I've read AGP aperture should be equal to the amount of video memory for fglrx, but my mainboard only allows up to 256M (512M on the 3850 card).
    Does your mainboard allow changing the voltage for your AGP card?
    I had to up it to 1.65V on my Abit Av8 with H.I.S. RadeonHD "Turbo Edition" 3850 AGP before 3d apps would run stable in either Windows or Linux. 2D apps and windows itself caused no problems at all at any voltage.(This required going to the voltages page in the BIOS and changing from "auto" to "manual" after which I could set the memory, CPU core and AGP voltages by hand.)

    At 1.55V or lower, the "VPU Recover" interrupts would happen about once every 5 minutes while 3D benchmarking or gaming in Windows XP.

    Plus another minus this card vs my old nvidia: my computer didn't shut down with this card. I hear that HDD is stopped, but video is on and I need to power off the computer hard. I have not this problem when I shutting down computer from windows or when using nvidia card.

    fglrx works really better with tv-out after I change from one DVI connector to another

    Maybe radeonhd works not so good as it can?
    (--) PCI:*(0@1:0:0) unknown vendor (0x1002) unknown chipset (0x9505) rev 0, Mem @ 0xb0000000/0, 0xc2000000/0, I/O @ 0x0000c000/0, BIOS @ 0x????????/131072

    I found a workaround how to watch dvb-s using xine (I have not this issue on nvidia cards). I need to run watching dvb-s, press alt+F11 (goes to console), and back from it (alt+F7) - than video looks like normal.
    This is not a very good workaround, because after switch a channel or stop playback - all hangs and monitor goes to black screen.
    I've switched back to stable but 3d and tv-out unsupported radeonhd and start search of ways to sold this unstable for linux card.

    I don't know the details, but my understanding is that the drivers can adjust the bus speed even if you don't have a BIOS option for the lower speeds.

    My motherboard doesnt support 2x agp mode. I have option to disable or enable AGP at 8x or 4x. But my old Nvidia GeForce Ti 4200 with 8x support works with 8x normally at the same linux or windows versions. My old GF 4200 supports 3d, tv-out, 8x, OpenSuse at the same hardware...
    Looks like HD 3850 doesn't support any of these.
