Nvidia driver 352.09-1.siduction.2 appears to be broken

[dibl]

Maybe this belongs in the "Experimental" forum, but if you have the experimental siduction repo enabled, then this issue will bite you in a dist-upgrade, so ....


This report is for one system only, so it is possible the problem is not for everyone.  On this system:

Code Select Expand

CPU:       Quad core Intel Core i7-4770 (-HT-MCP-) cache: 8192 KB
           clock speeds: max: 3900 MHz 1: 3400 MHz 2: 3811 MHz 3: 3621 MHz 4: 3637 MHz 5: 3766 MHz 6: 3541 MHz
           7: 3578 MHz 8: 3714 MHz
Graphics:  Card: NVIDIA GM107 [GeForce GTX 750 Ti]
           Display Server: X.org 1.17.1 driver: nvidia tty size: 142x68 Advanced Data: N/A for root


The new driver appeared to build correctly during the d-u, but the module failed to load when I restarted the X server (and after removing the prior module).  The kernel message in dmesg output was this:


Nvidia: unknown symbol swiotlb (err 0)


I removed the nvidia-kernel-dkms package and reinstalled it, and the module again appeared to build correctly, but would not load.


I commented out the experimental repo, removed all the nvidia-related packages, and then reinstalled 346.72-1.siduction.2, and it built and loaded correctly.

The user/experimental repo is not a repo, which should be used for normal work.
I put new drivers there, for testing.
fixes/unstable and fixes/experimental are the repos, where the working drivers can be found.


And yes, i know, the modules can't be loaded, i investigate it at the moment.

OK thanks towo.  I just wanted to alert anyone who lives on the edge like me.
