Description CIJOML CIJOMLovic CIJOMLov 2008-05-24 19:35:56 UTC
Hi there,

I upgraded from my last working commit version 

commit f69b48fe24ef94dac44b8123884ca71df675be4b
Author: Jesse Barnes <jbarnes@hobbes.virtuousgeek.org>
Date:   Tue Dec 18 18:10:33 2007 -0800

    Unconditionally restore pipe configuration

    This is a partial fix for #13196, which covers both leaving pipes disabled at
    server exit time and problems with restoring the pipe configuration on certain
    chipsets.  It restores the pipe configuration unconditionally (previously we
    made sure the PLL was running and we weren't in VGA mode) but also adds some
    additional PLL settle time to the PLL register write paths.
------------

to today's (20080524) git version and now my xorg crashes computer almost everytime when it starts. If not imeditially, so imeditially after switch to fb console.

I made git bisect, but last 3 bads are because problem compiling kernel.
Here is the log:

sorry problem compiling source.
Comment 2 Gordon Jin 2008-05-25 19:29:10 UTC
(In reply to comment #1)
> sorry problem compiling source.

Do you mean this bug report is invalid as a compiling issue? Or could you git-bisect to the exact culprit commit?

btw, I'm not seeing this issue with the latest driver.

The one which causes problems is:

Can anybody remove it from tree or solve problem it caused?

Thanks a lot

Comment 4 Eric Anholt 2008-05-28 15:04:26 UTC
Do you actually have the hardware that the commit in question affects?
Comment 5 Gordon Jin 2008-05-28 18:38:05 UTC
Could you attach Xorg.0.log? That commit only impacts a specific hardware, and I suspect it's probably not the one you are using.
Comment 6 CIJOML CIJOMLovic CIJOMLov 2008-05-28 23:45:47 UTC
Hi Gordon,

my hardware is Acer TravelMate 242 with Intel 852GME.
Comment 7 Eric Anholt 2008-05-29 12:08:53 UTC
Then I don't see any possible way it could be the commit you bisected to.
Comment 8 CIJOML CIJOMLovic CIJOMLov 2008-05-29 12:14:15 UTC
Don't ask me how bisect works - but now it runns again...I will add log from successful start with version I bisected and with latest git which crashes my computer. Give me sec...

Comment 12 Michael Fu 2008-06-22 22:34:45 UTC
anything fishy from the log, zhenyu? is there any other info or action we can ask michal to do?
Comment 13 Wang Zhenyu 2008-06-22 23:53:26 UTC
So 2.3.1 and 2.3.2 works for you, but git master failed? I think it's still FIFO issue we haven't resolved so far.
Comment 14 Michael Fu 2008-07-09 23:46:15 UTC
re-assign to Jesse. 
Comment 15 Jesse Barnes 2008-07-17 13:51:03 UTC
If it really is a FIFO issue, the latest patch in 16169 might help.  Can you give it a try?
Comment 16 Jesse Barnes 2008-07-17 13:51:51 UTC
Oh, you'll need to apply the patch to git master too, it has some other fixes for 855 as well.
Comment 17 Jesse Barnes 2008-08-20 13:16:28 UTC
I'm pretty sure we've fixed this one, please re-open if that's not the case, Michael.

Thanks,
Jesse
