Description of problem:
Running x11perf, dragging the scrollbar in mozilla, letting the
screensavers run: all of these are pretty good at locking up my machine (a
Steps to Reproduce:
1. install redhat 7.1 in "laptop" mode on thinkpad t20.
2. log in.
4. turn off screensavers in gnome control center.
5. x11perf -all
Actual Results: machine locks up hard. no response to keyboard, mouse,
or ping. requires power off, reboot, fsck, etc. really sux. :(
(to clarify: it does not lock up immediately. sometimes it takes a few
seconds, sometimes a minute.)
Expected Results: continued operation, lots of X11 performance data.
IIRC my thinkpad t20 is a model "2647-84U".
700 MHz, 256 MB, Savage IX 8MB, 1024x768.
it has a cisco aironet 340 wireless LAN card installed too.
but i removed the card and it made no difference.
in addition to trying stock redhat 7.1 right out of the box (i re-
installed it from scratch just to verify i hadn't done something wrong to
cause the problem), i tried using XFree86-4.0.3-11, XFree86-4.0.3-16 (?),
and, most recently, the latest from rawhide, XFree86-220.127.116.110-0.2.1
(with Mesa-3.4.1-1). also i tried using different version of gcc. also i
tried kernel-2.4.3-7 from rawhide, as well as "standard" (non-redhat)
linux-2.4.4. BTW all packages were downloaded in .src.rpm form, compiled
with "rpm --rebuild" and installed with "rpm -Fv". i didn't try ALL
combinations of ALL of these, but i've been struggling with this for a
while so i did cover a fair number... no luck in any case.
currently i am using stock redhat 7.1 + XFree86-18.104.22.1680-0.2.1, Mesa-
3.4.1, gcc-2.96-85, kernel-2.4.3-7. i also tried disabling DRI by
commenting out 'Load "dri"' in XF86Config-4.
any assistance would be appreciated; thanks!!!
PS a while back i had some weird problems (unreproducible ICEs) with gcc,
but that turned out to be bad memory. i ran "memtest86" and it reported
errors. i had the bad memory replaced and now memtest86 does not report
errors, and i've had no more weird problems with gcc.

Dave, isn't this the same laptop that you have? Could you perhaps
suggest something that might help?
My suggestion would first off be to get completely rid of the 4.0.99.*
that you got from Rawhide. It is completely broken, DRI doesn't work,
Mesa is mismatched and numerous other problems. It is a first shot alpha
build of an alpha quality software package. I don't consider any bug
reports on it valid as the package is not really meant to be in rawhide.
I accidentally built it in rawhide. All of the 4.0.3-* releases should
just be installed from binary packages for the best compatibility.
I recommend installing 4.0.3-16 or later (but not 4.0.99.*), and configure
it with: Xconfigurator --preferxf4 --nodri
thanks; i will attempt to do as you say. but already i have a problem. :)
where can i get a binary RPM of XFree86-4.0.3-16? i don't see it on rawhide or
people.redhat.com/mharris. (I have a source RPM from before, but I never
downloaded the binary RPM.)
Savage lockup problems are reported to be fixed in XFree86 4.2.0, which
is in rawhide and will be in our next release of Red Hat Linux.
thanks for the info; i really appreciate it!
BTW, i finally was able to swap hardware, just recently
when my laptop hard drive failed. i have a new laptop
(same exact model) running (vanilla, with updates) redhat
7.2 and i was quite thrilled when i tried "x11perf -all"
and it actually ran to completion no problem.
however, it still freezes when running screensavers.
now that i've disabled screensaver (whatever comes as
default in gnome), i have had no more lockups.
i'll look forward to the new releases and possibly check
out rawhide... thanks again :)
