Created attachment 835882 [details] patch to drivers/acpi/osl.c to put back export of acpi_os_wait_events_complete Description of problem: When I try to run a 3.13 series kernel compiled on my F20, it runs fine at the console, but when I try to start X using the nvidia proprietary drivers, it fails to load because the symbol acpi_os_wait_events_complete is unavailable. It turns out that the export of this symbol was dropped between the 3.12 and 3.13 kernels. I think it was by mistake, when the hotplug symbol was removed. Version-Release number of selected component (if applicable): 3.13.0-0.rc3.git1.2 How reproducible: Every time Steps to Reproduce: 1. Custom compile kernel on F20 2. Try to load X from multi user 3. X fails Actual results: Dec 11 11:54:10 localhost kernel: [ 18.302776] nvidia: Unknown symbol acpi_os_wait_events_complete (err 0) Expected results: X loads and runs Additional info: I patched the osl.c source to put back the EXPORT_SYMBOL, and the resulting kernel runs fine in F20. I'm running it as I type. I have attached the patch: I'm running the nvidia proprietary driver because the nouveau driver crashes regularly on my hardware. That hardware is old, nv4x, so the bug is unlikely to be fixed, since development is all on newer hardware. This started between 3.7 and 3.8. For my needs, a rock stable 2D driver, nouveau was preferable because of its seamless switch to console. Too bad.
In case it matters, I'm running Name : glibc Version : 2.18.90 Release : 15.fc20 Architecture: x86_64
We don't support proprietary drivers and the removal of the symbol isn't something Fedora did. It was changed upstream. Please email the authors of the relevant change and the linux kernel mailing list if you feel this was in error.
Thanks for the fast response.
