3.19 Kernel Enablement Hardware Stack to be default in Linux Lite 2.8

[Zead]

Make it optional. On Ubuntu LTS, you will get the newer kernel and drivers only if you install it manually or install Ubuntu point release from scratch.

The next 14.04 Ubuntu release (released in February I think) will have a kernel 4.x. It is supposed to have support for new AMD cards and other things. I think it will even have a support for Toshiba's sleep and charge USB.

In my opinion, It would be gould to ship the same (or newer) drivers and kernel like the Ubuntu LTS version Linux Lite is based on.

So Linux Lite 2.8 with whatever kernel 14.04.4 will have. Just to keep the real LTS experience .

@Jerry,
A final question,
If I wanted to report the "SDHCI Error" for non-existent H/W in the Kernel, where would I report that to.??
Googling shows lot's of kernel related posts across many locations..??

Thanks...

[Jerry]

That's exactly why I'm going to offer this upgrade as optional, situations like that

Update:
Kernel 3.19 did not resolve the above errors.
Kernel 4.2.0 "did" resolve all the above CPU errors.

I did end up with a "Slow WiFi Connection" issue, it was because latest driver not installed.

There is one last odd issue, giving an SDHCI error, and there is "NO" SD Card device on the NUC..??

@Jerry,

Based on my experience, and your target market I would "not" add it to your "standard" upgrade script.
I tried 3.19 on a PC that was giving me WiFi issues, whilst it appeared(?) to fix the WiFi issue,
I ended up with a "Kernel Taint" on a "Non-Existent" SDHC module. (shown in dmesg log file)
So for simplicity I rolled back the kernel, and I now re-start network manager every 12 hours.

I think adding it as an "option" is probably the best way, an optional "YES" - "NO" screen after you launch the upgrade script, with a "Warning".
and an instruction/reminder that if you "do" the kernel upgrade and encounter problems you will need to boot the previous(older) Kernel from
the "Advanced" grub option, Then use "Lite Tweaks" to remove the kernel just added.

Just my thoughts...

It's only because of building this NUC I brought the subject up... I certainly don't want to distract you from 2.8.

[Jerry]

I'm weary of adding 3.19 to the upgrade script, and wondering if this will cause a host of issues on otherwise rock solid systems around the world. I think the safe thing to do here is enable the repo, and make the kernel upgrade optional - with a warning.

[Wirezfree]

O.K.. Understood... I guess the answer was in the subject really...

From testing it appears to work, but there are 2 things in dmesg which appear to be an issue,
and actually have an indication for you to cut 'n' paste them to somewhere...
But where and would it be of any interest given the H/W and Kernel version..??

I think I may just try kernel 3.19, and see what happens.

[Jerry]

Ubuntu included it from 14.04.2, not Linux Lite. Ubuntu provides packages that LL either chooses to include or exclude. Choice of packaging, is the only comparison between LL and Ubuntu, or any other Ubuntu derivative for that matter.

[Wirezfree]

I'm a bit confused, or maybe just mis-reading this "LTS Enablement Stack"..?? it says:
"The 14.04.2 and newer point release will ship with an updated kernel and X stack by default"

We have version: LL2.6 14.04.3

Code: [Select]

dave@asus-mini-1:~$ cat /etc/*release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Linux Lite 2.6"
NAME="Ubuntu"
VERSION="14.04.3 LTS, Trusty Tahr"
or is this something you(Devs) can decide to enable or disable within LL development, and is currently disabled..??

The reason I ask is I'm trying to finish of a NUC build, currently on kernel 3.13
From basic testing everything appears to basically work O.K, or get recognised.
But "I can't test everything", and everything I've read seems to be imply that
NUC "Broadwell" needs Ubuntu 15.04 & kernel 3.19

[Jerry]

There's unlikely to be a huge list of changes in this the last release of the 2.0 series, I'd like to have as much hardware support as possible leading up to the 3.0 series. Have started running some simulations, so far so good.

@Zead..
Kind of on topic...
I will be updating a thread I have else where on installing LL to a friends New Intel NUC517RYH

I was surprised, the NUC contains one of the new M2 NVME pcie SSD's
This was only partially supported in Win8.1, full support now in Win10
My friend wanted LL dual boot with Win7    what a performance..
It's not even visible in Win 7,
So had to install Win7 to a 2nd normal drive,
then install 2 hotfixes, then clone to M2 drive
Tested for a few days, make sure it's O.K


I have done a Live boot of LL,

The M2 drive shows up out of the box, +1 to Linux
Also, the Display "Iris 6100 Graphics" came up.
I plan to try and install LL later today.

[Zead]

Graphics drivers and other drivers too?
