Comment 5 Gordon Jin 2008-10-09 06:02:40 UTC
Quanxian, could you describe the connection type: which port (DVI?) used on the board?

You told me the same package works fine on SuSE 11.0. Is it with the same connection cable and monitor?
Comment 6 Wang Zhenyu 2008-10-09 18:31:00 UTC
Looks like #17892 is dup with this, and my patch is on that one too.
Comment 7 Gordon Jin 2008-10-09 19:30:16 UTC

*** This bug has been marked as a duplicate of bug 17892 ***
Comment 8 qwang13 2008-10-16 01:08:44 UTC
I do the testing on RC4 packages. Still not works. Also I have tested RC3 with Zhenyu's patch, it also doesn't works. Seems this problem is not same as bug 17892.

Also I got some information from dmesg.
[  179.709708] [drm:i915_getparam] *ERROR* Unknown parameter 5
[  180.380260] set status page addr 0x02aa0000
[  180.460556] [drm:i915_getparam] *ERROR* Unknown parameter 5

Any suggestion for this?

Comment 9 qwang13 2008-10-16 01:11:48 UTC
By the way, 
This time stack trace(comment #4) disappears. The port is VGA not DVI.
Comment 10 Gordon Jin 2008-10-16 02:01:35 UTC
Quanxian, have you changed to from Ubuntu's kernel to GEM kernel?

The dmesg in comment#8 does not exist in your first dmesg (in comment#3).
Comment 11 Wang Zhenyu 2008-10-23 19:19:54 UTC
We have already fixed a crash relate to display output probe in 2.5.0, this should be fixed, close this, reopen if you still see this.
Comment 12 qwang13 2008-10-23 19:32:18 UTC
Sorry to response later.

Would you like to push the fix commit to this bug for us to tracking?

We have two commits might be relate to this one.
commit 986c8df79e83c369655ad786a6bf6342b53c535d

    Fix Mac mini crash in DDC mode probe
    SDVO on Mac mini trys to get EDID from CRT port, which
    failed with recent DVI-I change.

    Bug #17892: Fix possible crash in CRT probe
    Introduced in patch for DVI-I CRT probe, if no EDID
    CRT monitor is connected, origin code destroys default
    DDC bus which causes crash in later get_modes call.
    Change it to setup and destroy DDC bus as needed in
    get_modes, so we always reprobe and get current state.
