Description of problem:
Everytime I try to start the XServer either by using the startx
script directly or starting in runlevel 5, my computer completely
locks up and becomes unresponsive for over 4 minutes. The keyboard
doesn't respond and the screen is blank. There is no disk activity.
It seems like the whole machine is dead. I also cannot switch to
another console while its locked up.
After the 4 plus minutes have elapsed, all the sudden the disk drive
starts going really heavy and the desktop appears within 15 seconds.
This is what it used to do under RedHat 6.2. The XServer under 6.2
would just come up immediately.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.login to the machine
Actual Results: As I explained in the description
Expected Results: I expect the hard drive to crank and put up a
display and desktop within a reasonable amount of time, without my
computer locking up rock solid.

My XFree86 startup log
I128 video hardware is very old, and the I128 driver is more or
less unmaintained upstream for quite some time. Since we do not
have this ancient hardware, nor it's specifications, there isn't
much we can personally do about i128 driver malfunctions other
than to try to narrow down the problem with you, and try to isolate
the problem area of the driver.
In order to troubleshoot, please add the following to the driver
section of your config file:
After rebooting the machine, in order to reset the video hardware
to it's default power-on state and ensure it is not misprogrammed,
please start the X server with "startx" and see if the crash you
were observing has disappeared, or is still present. Please indicate
wether it works or not.
If it does seem to make the problem go away, remove the noaccel
option, and now we can try to determine which of the acceleration
primatives are related to the problem you're experiencing. To do
that, please read the XF86Config manpage, where you'll find a number
of options listed that start with XaaNoxxxxxxx. Please try each of
these options one at a time, restarting the X server (or your system)
between each invocation, to see if the given option works around
the problem. If the X server does start and seem to work, please
exercise it a bit to see if it is stable. Indicate here if any
single XaaNo option, or group of options results in a stable display
Once you've done this experimentation, please attach the log file
and config file from any noteable configurations which worked and
any others that you think might aide in finding a solution. Also,
attach at least one copy of /var/log/messages, and the output of
"lsmod" from your running system under X, as both contain valuable
information useful for troubleshooting. All files attached should
be individual uncompressed files, one per attachment, browser
viewable, like the above log attachment you've provided.
Once you've provided the results of your troubleshooting, I can
investigate a possible resolution.
Using "noaccel" option in the drivers section made no difference.
I think you misunderstood my problem. There is nothing unstable about
the XServer at all once it starts. It is rock solid and much faster
than the RedHat 6.2 version by a bunch. My problem is a spli second
after I type startx, I get a blank screen for over 4 minutes in which
the keyboard is completely locked out. After the 4 minutes have
elapsed, the XServer starts normally and everything works great.
I do have some more information now though. I got a slick idea to
telnet into my machine remotely while it is hung up to see if I could
dump the XFree log file and now know exactly at which line in the log
file in which it is hung up at. When I did this I found the lines that
were written in the log were these:

It seems to me, the XServer is getting hung up scanning my PCI bus.
What do you think? I'll upload my messages and lsmod files too.

It seems that way. Hard to conclude anything though without more
information. Can you attach your X server log file as a bugzilla
It is very likely that fixing this problem will require manual
debugging of the X server directly on the problem hardware. Are you
skilled at all in debugging with gdb? If so, do you have 2 computers
connected on a LAN?
FWIW, I've experienced this problem with more modern hardware, on
various Linux distributions. Typically it happens when there is some
sort of DNS misconfiguration and the machine is not able to look up
the name that corresponds to its own IP address...
I forgot I still had this bug open in the database. I can use gdb,
not very skilled at it though. I can no longer experiment with the
machine however since in the last few months, Fedora 2 came out, I
tried it, and it fixed both the SMP crash problem and my slow video
start. X now starts up very fast, as it did before. So I'd say you
don't need to spend any more time to fix this, as anyone with this
problem could probably use the X-server in Fedora 2 and get rid of
Note to Barry, it was not a DNS problem, I know that for sure. The
X-Server was hanging during PCI bus scan in my case. This hang went
away with the new Fedora 2 kernel.
Since this bugzilla report was filed, there have been several major
updates to the X Window System, which may resolve this issue. Users
who have experienced this problem are encouraged to upgrade to the
latest version of Fedora Core, which can be obtained from:
If this issue turns out to still be reproduceable in the latest
version of Fedora Core, please file a bug report in the X.Org
bugzilla located at http://bugs.freedesktop.org in the "xorg"
Once you've filed your bug report to X.Org, if you paste the new
bug URL here, Red Hat will continue to track the issue in the
centralized X.Org bug tracker, and will review any bug fixes that
become available for consideration in future updates.
