Hi, few weeks ago i've upgraded kernel to 2.6.15 and ati driver to 8.20.8, but the system crash with kernel panic. I've erased the agpgart module and the system work fine, but without DRI.
Today i've seen the new x.org version, i've upgraded all but the problem reappear.
I've recompiled 2.6.14.5 and the system work fine, with agpgart loaded and dri enable.
system log:

There's a known fix for this
Go to line 2624 of firegl_public.c
Ignore all the warning messages in the comments.
Replace the #ifdef 0 with #if LINUX_VERSION_CODE >= 0x02060f
Recompile the ATI module, reinstall it, and reboot.

Hello,
Could you please explain better your solution ?
I've two files firegl_public.c:
/lib/modules/fglrx/build_mod/2.6.x/firegl_public.c
/lib/modules/fglrx/build_mod/firegl_public.c
Which one is to edit ? (There isn't difference between the files)
At line 2624 I have:
#if 0
// WARNING WARNINIG WARNNING WARNNING WARNNING WARNNING WARNNING WARNNING
// Don't increment page usage count, cause ctx pages are allocated
// with drm_alloc_pages, which marks all pages as reserved. Reserved
// pages' usage count is not decremented by the kernel during unmap!!!
get_page(pMmPage); /* inc usage count of page */
#endif
#if LINUX_VERSION_CODE >= 0x020400
__KE_DEBUG3("vm-address 0x%08lx => kernel-page-address 0x%p\n",
address, page_address(pMmPage));
return pMmPage;
Must I replace #if 0 with #if LINUX_VERSION_CODE >= 0x02060f ?
Thanks a lot.
BR,
Fabrizio

Ops, sorry. The first is a link to the other file, but #ifdef 0 there isn't..
Thanks again
yes, replace the #if 0
That's what I meant. It works for me...I found it on a few other web sites but I forget where right now and don't have time to look again.
And yes the one file is a symbolic link, so it shouldn't matter which one you open in your editor.

You looking for this patch I think. Make the below a diff ;)

I can confirm that this solves many problems including the strange hangs in many x apps.

Sorry about no code formatting, but for some reason doesn't process the above correctly.
