WARNING: "__call_bad_lock_func"
[/var/lib/dkms/fglrx/8.602/build/2.6.x/fglrx.ko] undefined!

** Changed in: fglrx-installer (Ubuntu)
       Status: Incomplete => Confirmed

** Description changed:

  When booting a generic kernel (2.6.28.11.15)  X comes up fine, with 3D
  accel, compiz, etc.
  
  When booting a realtime kernel (2.6.28-3-rt), the fglrx module appears
  to be loaded fine thru DKMS, but I get a corrupted screen when GDM
  loads. I can switch to a VT once, which just gets me a different
  corrupted screen, and I can't do anything from there, even flying blind.
  
  
  Here's the output snippet from the gdm log, looked at after rebooting to the generic kernel:
     
  FATAL: Error inserting fglrx (/lib/modules/2.6.28-3-rt/updates/dkms/fglrx.ko): Unknown symbol in module, or unknown  parameter (see dmesg)
  (EE) fglrx(0): [FB] Can not get FB MC address range.
  (EE) fglrx(0): atiddxDriScreenInit failed, GPS not been initialized.
  (EE) fglrx(0): XMM failed to open CMMQS connection.
  [glesx] __glESXExtensionInit: No GL ES2.0 capable screen found!
  
  
  Here's the kernel message I got from dmesg:
  
  fglrx: Unknown symbol __call_bad_lock_func
  
+ From stack trace during compile:
