Good morning Philip,
- To install a most vanilla kernel elrepo is a quick step look forward about kernel solution
- Yes build own kernel by a special kernel specification for your machine. Why not?
- Frozen a kernel in fact „it works“ with the right firmware for your wifi is a good solution.
I got a mixed network with Windows 3.11 up to Windows 10 and Linux with OpenSuse, Ubuntu
and a HPC Centos 7 Cluster on Opteron 6380.
By the way, when you get a preinstalled System on a laptop it works in most cases from prebuilder.
It’s a common thing to use the given driver. To upgrade it all the time by update can hold you back
todo you real work.
As hardware, network and software specialist i try out different compositions. My private iMac 2010 not
run really on the 2.6 - Centos 6 or 3.10 kernel form Centos 7. Same effect on newer hardware from „today“.
To build the right kernel for specific hardware is for me a common thing. Freeze it when i got - also.
We froze the HPC cluster at 7.1.503, because it works for us. To update or upgrade can not be done all the time,
our calculations run from hours to month….
Some of you say Centos 7.0 works why not download this kernel from vault.centos.org <http://vault.centos.org/> and install with yum install kernel…rpm?
Sincerely
Andy
