From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705) Description of problem: I have an ABit SE6 with Intel 815E integrated graphics & audio. Initially, I thought this was a RH 7.3 issue since it happened immediately after installing and didn't happen on RH 7.2 or Mandrake 8.2. However, after more testing, it also happens under RH 7.2 if I update the kernel past the base 2.4.7-10. What happens: Upon logging into KDE, all seems well at first. After a short period of time, the screen will simple go black andc I'll be back at the login prompt for X. Under GNOME, application and bus errors will popup for anything running and I'll be lucky if I can get it to log out. I currently have both the 2.4.7-10 and 2.4.9-34 kernel's installed and can run flawlessly under the 2.4.7-10. If I boot into the 2.4.9-34, it will immediately start going crazy. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Load into Kernel 2.4.9-34 2. Run Theme Selector under GNOME and select a theme 3. Use the arrow keys to flip through all the themes and within 1 minute, everything goes haywire. Actual Results: GNOME: Window title bars disappeared, any opened programs I could get to appear would appear in upper left w/o titlebar, panel sometimes disappears, taskbar flashes programs on and off, bus and application errors pop up. Expected Results: Nothing - it should work without issue as it does under kernel 2.4.7-10 Additional info:
What XFree86 version-release are you using? Please attach your X server log and config file. If you're not already using all released errata updates, please update your system with up2date and provide new information in the bug report also. Thanks.
Ok... no problem. I'll post the logs shortly... but as for the errata updates, all are installed. Thanks.
You never did attach those logs... At any rate, the Intel i8x0 kernel DRM code was changed by Intel in an ABI incompatible way, which broke the driver. It's released and in production, so there is no way to properly "fix" it. Many great thanks to Intel for this wonderfulness. Anyway... Our latest kernel has an ugly hack workaround for this issue by plopping some crap in /etc/modules.conf which instructs the kernel which ABI to use. The kernel keeps both ABI's present internally, and if modules.conf is set correctly, it should work properly. This same issue occurs for Red Hat Linux 7.3 and 8.0 also. DRI developers have since discovered another hackish way they can autodetect this at runtime somehow and XFree86 4.3.0 should come with this code by default. We might backport the fix as well, but since it is quite nasty, we might just leave it with our existing hack that seems to work. If you still experience these problems even after applying the latest erratum to 7.[123] or 8.0, please reopen the bug report if you like.
I apologize for not following up on this... I ended up dropping Linux because of the issue and haven't touched it since... I may in the future pick it up again and explore some more but right now, I do not have the time. Thanks again.
Ok, if you start using Linux again (c'mon, you know you want to <grin>) and the problem manages to pop up for some reason, please reopen this report if you like, or file a new one against the newest release. Thanks again, TTYL
