Bug 9206

Something alike here. After starting X I got 99 persent of system resources 
occupied by X and that is looks like somekind of loop. My log file stops at
(II) Loading /usr/X11/lib64/modules/libint10.so 
(II) Module int10: vendor="X.Org Foundation" 
 compiled for 7.1.0, module version = 1.0.0 
 ABI class: X.Org Video Driver, version 1.0 
(II) TDFX(0): Softbooting the board (through the int10 interface). 
Fred, you are saing you finally start X. How?

No TDFX line, of course, and sometimes it was a hard lock-up.

I worked around it with the following patch in the
xorg-server-X11R7.1-1.1.0/hw/xfree86/x86emu/decode.c file:

It is a hack definitely.  The magic number 4541000 may not work for you.  When I
leave X to return to the console, the display on the softboot-ed adapter is
messed up.  It used to say something like, "ATI MACH64 P/N BIOS".  Now, it's
garbage.  But at least I can get into X.

Ye a i got it form your first message. And already made it. I didn't get the
root of the evil. Why it hangs in the loop? Any way I suppose the bug is not
take place in my configuration. I've made a mistake I did compile the X server
with 2.6.19 kernel source and that is wrong. What I did: I modified loop same
way you are talking about and added printk in the end of loop like: if
(cnt>=4541000) {printk("loop finished at cnt = %i",cnt); And there was no
messages appasred in log after X starts. So I remove patched string and came
back to the original source and recompile xserver with 2.4.28 kernel headers. No
I can assume that the infinite loop take no place for me. Sorry for disturb. Let
 as know if thing will change.

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.
