Bug 108957 – ATI drivers can't be loaded with kernel 2.6.14-rc3

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Christine Bussman 2005-10-11 20:49:05 UTC]

ati-drivers 8.14.13-r2 compiles against kernel 2.6.14-rc3, but cannot load.  The
result as it shows in dmesg is "unknown symbol verify_area".  A web search seems
to say that this is a known problem that can only be fixed by ati, but it would
be helpful if either there was masking/blocking to avoid the problem or at least
a warning.  

Reproducible: Always
Steps to Reproduce:
1.compile a 2.6.14 kernel, and boot into it
2.emerge ati-drivers
3.modprobe ati-drivers

Actual Results:  
modprobe fails, dmesg gives the message listed above.

Expected Results:  
loaded the module

What about the newer versions of ati-drivers?

[Comment 2 Gregor Riepl 2005-10-12 01:57:26 UTC]

This is broken with any version of ati-drivers... 
verify_area has been replaced with access_ok a while ago and now is removed 
from the kernel. 
 
Anyway, Bigneotux provided a patch in the forums (and I basically did the same 
change on my installation). Maybe someone should include the patch until ATI 
fixes the problem?

I'll add to the patchset soon, Joshua if you have time could you please test it
on amd64 or x86?

(the right patch should have a ifdef to let old kernel users have the module
working)

[Comment 4 Joshua Baergen (RETIRED) 2005-10-12 08:17:30 UTC]

I don't have access to ATI hardware anymore unfortunately...

[Comment 5 Luca Barbato 2005-10-20 03:27:20 UTC]

resolved with a sed solution.
