While using Firefox, my computer likes to occasionally spontaneously and instantaneously reboot - no warnings, nothing - browsing one second, POST screen the next. Notably (?), my RAID 1 (non-root FS) does not do a rebuild on startup (does this imply a kernel panic or rule out hardware issues?). If I continue to return to the page I was viewing (Firefox offers to restore the session), it would happen again and again - maybe not instantly, but usually if I scroll the page at all. It took me some time to isolate any apparent commonality among the pages causing this: They all seem to contain fairly large images which are displayed scaled down in the web page. Viewing those same images full size causes no problems. I have an Intel DQ965GF motherboard ( http://www.intel.com/products/motherboard/DQ965GF/ ) and a Core 2 Duo with 4GB RAM, using the onboard Intel 965 video via a DVO/DVI card, running Fedora 8 with all patches applied, in pure x86_64 mode (all i?86 packages removed). I'm not sure what exactly to file this against, but I'm gonna guess at the i810 driver for starters (knowing Firefox has a close relationship with the X server, and that with the Kernel). Thanks for any clues or assistance you may provide! :)
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. Which URL it is? Do you have some other suggestions how we could reproduce this problem on our computers? We will review this issue again once you've had a chance to attach this information. Thanks in advance.

Well, the last time I reproduced this bug, I was sending a message to my friend on Facebook, and sent a picture of my motorcycle which I found on the net: http://www.totalmotorcycle.com/photos/2005models/2005-Honda-919.jpg So, hopefully you have Facebook? :) Go compose a message to yourself... enter a bunch of lines of "test" or whatever to make it so you can scroll, then paste that URL in and send it. Facebook should automatically include a "thumbnail" (scaled down reference) to the image in the message. If I do this, and scroll up and down in the message for about a minute... poof! I had it crash almost instantly the first time I sent the message to my friend... but this time doing it to myself, I had to scroll for a whole minute, long enough that I almost thought it wasn't reproduceable. I wonder if it's because the computer had just been restarted after the last crash, and the browser was fresh, and the problem is some kind of video memory leak or something that takes time to build up. Let me know if there is anything else I can do! :)
So, it just occurred to me (duh) that I had components for a second box which is basically identical to this one (which I'm gonna build a HTPC/PVR out of)... so I just hooked it up and boot the Fedora 8 Live CD on that, and I can't reproduce this :( This makes me think maybe this is a hardware problem (bad ram in the AGP aperature maybe?). I'm gonna close this, and will reopen if I can reproduce on 2 machines. Sorry for the bother.
