Re: Compiler errors when compiling 180.44 for 2.6.30-rc1
this was explained few times (search for similar problems with 2.6.29/2.6.29-git error appeared in 2.6.29-git9 after "owner reference was removed from the kernel) already:
remove "owner" reference from nv.c
this will work until nvidia fixes driver.
Your kernel is beta by the way, so you should fix this yourself until nvidia adjusts driver.
