Description Jay Fenlason 2008-09-19 16:21:26 UTC 
Description of problem:
When I upgraded my kernel from -113 to -115 the nvidea.ko module stopped loading with 

Version-Release number of selected component (if applicable):
2.6.18-115.el5

How reproducible:
Always

Steps to Reproduce:
1.Boot the -115.el5 kernel
2.copy nvidea.ko from /lib/modules/2.6.18-113.el5/kernel/drivers/video/nvidia.ko to /lib/modules/2.6.18-115.el5/kernel/drivers/video/
3.run depmod
4.Attempt to start X with xinit
5.
  
Actual results:
X fails to start.  The error message says to look at dmesg, which says:
eth0: no IPv6 routers present
nvidia: module license 'NVIDIA' taints kernel.
nvidia: disagrees about version of symbol acpi_bus_unregister_driver
nvidia: Unknown symbol acpi_bus_unregister_driver
nvidia: disagrees about version of symbol acpi_bus_register_driver
nvidia: Unknown symbol acpi_bus_register_driver
nvidia: disagrees about version of symbol acpi_bus_unregister_driver
nvidia: Unknown symbol acpi_bus_unregister_driver
nvidia: disagrees about version of symbol acpi_bus_register_driver
nvidia: Unknown symbol acpi_bus_register_driver

Expected results:
X starts

Additional info:
This module worked fine up through -113.
Comment 2 Don Zickus 2008-09-23 13:34:05 UTC 
The symbol acpi_bus_unregister_driver is not on our whitelist of symbols we promise not to break.  Unfortunately, you will have to recompile the module to pick up the changes.

You can propose we add that symbol for 5.4.0
