Failed compile with Fedora kernel-2.6.34-11.fc14.x86_64

[BoscoBearbank]

Using NVIDIA-Linux-x86_64-256.25.run (but also tried NVIDIA-Linux-x86_64-195.36.24-pkg2.run with the same result) with Fedora Rawhide. No problem compiling with kernel-2.6.34-0.28.rc3.git3.fc14.x86_64; failure with kernel-2.6.34-11.fc14.x86_64 (GPL-incompatible module nvidia.ko uses GPL-only symbol 'debug_lockdep_rcu_enabled'). nvidia-installer.log file is attached.

Can someone point me to a simple way to find the code that needs to be modified to work around GPL-only symbol errors such as these? Otherwise, all I can do is wait for someone else to deal with the problem.

Thanks

Did you compare the kernel configs? IIRC, there used to be some option to allow/disallow some GPL-only symbol export linking stuff..

My guess is that the new kernel was built with CONFIG_LOCKDEP, and that this option once again causes third-party modules to implicitly pick up GPL-only symbols (see e.g. http://www.nvnews.net/vbulletin/show...hlight=lockdep) for previous reports of similar problems.

Nothing obvious, so I tried

/boot$ grep -i lockdep config*
config-2.6.34-0.28.rc3.git3.fc14.x86_64:CONFIG_LOCKDEP_SUPPORT=y
config-2.6.34-0.28.rc3.git3.fc14.x86_64:CONFIG_LOCKDEP=y
config-2.6.34-0.28.rc3.git3.fc14.x86_64:# CONFIG_DEBUG_LOCKDEP is not set
config-2.6.34-11.fc14.x86_64:CONFIG_LOCKDEP_SUPPORT=y
config-2.6.34-11.fc14.x86_64:CONFIG_LOCKDEP=y
config-2.6.34-11.fc14.x86_64:# CONFIG_DEBUG_LOCKDEP is not set

Given that I'm running Rawhide, it's not a pressing issue. However, knowing where to look for the fix would be nice.
