Thanks Trulan ... just needed to verify since linux-image-4.8.6-rt5avl2_4.8.6-rt5avl2-2 apparently did not offer Nvidia/Ati support ... that's why I upgraded to the 4.9 LTS ... I do a lot of audio/visual work and am looking to purchase a graphics card for video transfers, so I needed the info ... linux-image-4.9.33-rt23avl1_4.9.33-rt23avl1-3_amd64 runs smooth as silk on my MX-16 setup!!

Cheers

Tx Trulan, it sounds simple enough for me.

Just clarify, I have the following:

Quote

-Computer-
Processor      : 8x AMD FX(tm)-8320 Eight-Core Processor
Memory      : 16419MB (3581MB used)
Operating System      : Debian GNU/Linux 9.1
Kernel      : Linux 4.9.33-rt23avl1 (x86_64)

It sounds as if I installed a regular Debian kernel 4.9 LTS I might unlock more features for my graphic card.

The last question I have is where do I get the 4.9 LTS kernel? I don't see it under the Synaptic Package Manager.

Thanks for any help you can offer,

Hi everybody!  There's a new batch of kernels for your testing, usage, and enjoyment.  This time, there are four kernels available:

For 32 bit: (i386)
linux-4.9.40-rt30avl2
linux-4.9.40-lowlatency-avl2

And for 64 bit: (amd64)
linux-4.9.40-rt30avl2
linux-4.9.40-lowlatency-avl2

The 'rt' kernels are updates to the Real Time Linux kernels you are familiar with in AV Linux.  A Real Time kernel often can perform more consistently at low latencies under heavy load.  (ie, fewer xruns while processing live audio.)

The 'lowlatency' kernels do not include the 'Real Time' patch.  Some hardware does not play well with a full real time kernel, especially hardware that requires proprietary drivers (such as many NVidia video cards).  If you would rather have good graphics and no headaches, and don't care about crazy-low latencies, then these kernels are for you.   Many users will not be able to tell a difference between the real world performance of the two kernels.

As always, I appreciate those of you who test and report back!

Is there a tutorial/video anywhere for me to try testing, I'd love to have a go if it's not TOO  :rolleyes: complicated  :cheesy:

Hi,

They just install like any other package from Synaptic, just search:

linux-4.9.40-rt30avl2 or linux-4.9.40-lowlatency-avl2 (depending on what you're looking for) in Synaptic and you can install them, this won't remove your existing kernel and on next boot GRUB will automatically select the newest kernel on the system. If everything works you can later decide to uninstall the previous older kernel using Synaptic as well. If the new kernel doesn't work for some reason or you don't like it, simply select the 'Advanced Options' in GRUB with your keyboard arrow keys on your next boot and select to boot the older kernel and then remove the new kernel using Synaptic...

Easy Peasy! :cool:

Now... if you want to install nVidia proprietary drivers on the lowlatency kernel that is a bit more involved and I am going to document it soon...

I know, I just pushed out a set of kernel updates a few days ago.  But there were a few fixes in the recent upstream updates (including an important fix in the alsa-firewire driver) that I wanted to get out there.  So you will find a set of 4.9.47 kernels (rt and lowlatency) in the repository.  So, there they are, and happy testing!

Ha

I haven't been able to get any kernel after 4.6 rt to load always  gives a udev permission problem.

Kernel boot error:

Scripts/init-top/udev  line 14 Cant create/sys/kernel/uevent_helper: Permission denied

dosent find the drive.

I noticed a search for "linux-4.9.40-rt30avl2" and "linux-4.9.40-lowlatency-avl2" yielded nothing for me. When I removed linux, i.e "4.9.40-rt30avl2 or "4.9.40-lowlatency-avl2" they showed up.

Not sure if this is a problem on my side. Sure got a few of those :)

Hi Joe,
Thanks for the report.  That looks like this bug:  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=752742
Are you running a rather old installation of AV Linux?  If so, you may need to upgrade systemd to get past this.  Even debian jessie (old stable) systemd package has been patched for this as far as I can tell.

@GMaq, have you seen any issues like this on your machines?  There's a workaround kernel config option I can enable if I need to.

Trulan just pushed an updated '4.9.47' kernel, it's possible he replaced 4.9.40 so it no longer appears. I've been busy with work and am a little behind testing right now.

Hi,

Sorry busy with work and am behind on kernel testing, 4.9.33 works well for me (other than some Virtualbox stuff which we already discussed) so I'm assuming 4.9.47 will if there were no changes, I need to catch up and sync all my builds next weekend.

From Joe's other posts I think he had networking issues with AVL 2017 and is remarkably still using AV Linux 6.0 (which doesn't have systemd at all)

@Joe, AVL 6.0 is discontinued and obsolete, it's cool if it still works for you, but we can't be making kernel adjustments and alteration to accommodate an obsolete version.
