kernel
My B+ appears to boot properly however it shows an orange warning marker on one line and says ' Kernel lacks c groups or memory controller not available , not starting c groups". Am using a pre-loaded micro card from Amazon. Help Please, Newbie Don

Ignore it, it's not important.

Re: kernel
If it really worries you, try this solution
add line : cgroup_enable=memory (before elevator=deadline)
cgroups is a relatively new low level configuration tool for Linux kernel behaviour that is expained here: https://www.kernel.org/doc/Documentatio ... groups.txt. It is not really something that the new user needs to worry about (or would even understand?)
The checks into how useful cgroups are for the Pi came out neutral; it uses a little memory and does not add a lot. Not using them gives this message. This issue is one for the experts to consider
Code: Select all

Re: kernel
Hence my reply. It's a kernel addition that's 100% pointless. I'm surprised Linus T. let it get added since he vociferously dislikes (with lots of swearing) things that are broken or useless.Navyscourge wrote: The checks into how useful cgroups are for the Pi came out neutral; it uses a little memory and does not add a lot.

Re: kernel
From what I've read, it seems to want to give each user an 'almost virtualised' portion of the available resources. It sounds much like VM/CMS which was introduced ~50 years ago.DougieLawson wrote:Hence my reply. It's a kernel addition that's 100% pointless.
