avsa242-mesa git glxinfo
Confirmed with mesa git handbuilt (./configure --prefix=/usr/lib/opengl/handbuilt/ --enable-xcb --with-dri-drivers=r300,radeon,swrast --disable-gallium --enable-debug), xf86-video-ati git (live ebuild, x11 layman overlay) xorg-server git (January) on Gentoo, gcc 4.3.3. RS480 XPress 200M 5955. Mine hits the assert in r300_texstate.c instead; numLevels=13 I can confirm this bug. I can reproduce it every time with ubuntu 9.04 beta and before that with ubuntu 8.10. Flightgear crashes with the following message:
*********************************WARN_ONCE*********************************

(In reply to comment #4) I forgot to say: compiz is off; my video card is ATI mobility radeon x1400. I also tried flightgear with the proprietary driver and it works without problems then.

Nope, this bug and other fog related has been fixed by d8b8fb68954e6eebd0b38708c25a5bec4cf1a26c and 7ad7abc4cd5c94b83feea4553ffb5a69d8ad4757.

If you apply the two patches mentioned above to 7.4, does it fix the issue? I may release Mesa 7.4.1. on Friday... (In reply to comment #9) > If you apply the two patches mentioned above to 7.4, does it fix the issue? Unfortunately, I have no idea how to do that. (In reply to comment #9) > If you apply the two patches mentioned above to 7.4, does it fix the issue? > > I may release Mesa 7.4.1. on Friday... > I'd suggest not to include those patches even if they would fix the issue. They are pretty invasive, touch sensitive area (incorrect RS setup can easily lockup GPU) and weren't tested separately that much (but the whole patch-set from 2009-03-06 has been tested thoroughly on r300, r400 and r500 cards by Markus Amsler and on rs690 by me). Also d8b8fb68954e6eebd0b38708c25a5bec4cf1a26c patch depends on 25dfbb03f8acf91a707d722af2336821dd73b8ff. Created attachment 24870 [details] [review] patch fixing failing numLevels assertion Attached patch should fix the failing assertion (it's against mesa_7_4_branch). In r300CreateContext we set max texture levels to 13 for >= RV513, for earlier cards we leave it to default (12). In r300SetTexImages we were checking numLevels against RADEON_MAX_TEXTURE_LEVELS (12) instead of actual limit. (In reply to comment #12) > Created an attachment (id=24870) [details] > patch fixing failing numLevels assertion That's not enough to handle >12 levels in general though. Have you tried backporting e101959b6a262ba34a12b407ea6f480e6b4d7d72 from master? (Though your change may make sense on top of that - I was just taking the assertion as guarding against array overflow) We could backport e101959b6a262ba34a12b407ea6f480e6b4d7d72 as Michel Dänzer said, but you still would hit "Don't know how to satisfy InputsRead=0x00000008" problem (which would probably hard lock the GPU). Patches that fixes it are too invasive and won't be backported. The best resolution for you is to upgrade mesa.

Maybe it's one of the RC releases. I am still able to reproduce the exact same bug as in the description with this RPM version on the same hardware. Let's keep this bug in the resolved state while I get a chance to verify if it has been fixed. Please do not mark this bug as closed until then. The source file of the assertion is different, but it's in the same function, so maybe the file was renamed: [muks@naina ~]$ fgfs Model Author: Unknown Creation Date: 2002-01-01 Version: $Id: c172p.xml,v 1.20 2008/09/01 15:14:33 torsten Exp $ Description: Cessna C-172 FGMultiplayMgr - No receiver port, Multiplayermode disabled KI266 dme indicator #0 initialized Initializing Nasal Electrical System fgfs: radeon_mipmap_tree.c:142: calculate_miptree_layout: Assertion `numLevels <= 12' failed.
