Is this a stable kernel?

Tue Sep 11, 2018 8:28 pm

Topic says it all, i just did a sudo apt-get update and sudo apt-get upgrade, rebooted my Rpi and got Linux 4.14.69-v7+. Is this stable?

With Raspbian if you apt-something you are in stable territory.

It's unusual for a kernel to be available on rpi-update on Monday and pushed to everyone with apt-get on Tuesday. It's probably stable enough, but I'm not sure it's gone through enough early testing.

Oook.. I thought apt-get was the best way to get the pi updated
to a stable kernel?

It is stable because it's the one that the RPF folks have blessed. They're going to avoid delivering kernels and bootcode that has nasty bugs because it will cause them a bucket load of pain.

It als means everyone is working from the same base level.

It is, but at the moment the repo version (apt) is the same as the github/firmware (rpi-update) one

I'm confused, does this mean that the stable kernel is actually still In Testing?

yes - sometimes release will match bleeding edge

Not really, it means that the previously under test kernel has now been released, but we don't yet have a new testing kernel in rpi-update. Internally we do of course, and rpi-update will surely be updated fairly soon.

There seems to be a problem with kernel panics on shutdown when Bluetooth is disabled with the latest supposedly stable 2018-09-10 firmware. Several threads from users experiencing this problem. I first tested it on my Raspbian Stretch Desktop system and could not reproduce the issue.

But then I upgraded my Raspbian Lite system and it failed on shutdown with a kernel panic. Tried it with a freshly imaged drive, and the same thing happened after update/upgrade (kernel panic on shutdown). So I would have to say, no, this isn't a stable kernel/firmware release.

I rolled back to the last stable commit with,

Code: Select all

sudo rpi-update 911147a3276beee09afc4237e1b7b964e61fb88a
followed by a reboot. Now I'm back on kernel 4.14.62-v7+ and no more panics (shutdown works as expected).

I'm not 100% certain, but the issue may only happen on USB booted systems.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

Hmmm... I think I will rollback to the previous kernel and wait a week or so before upgrading again, in using a HDD to boot into raspbian through PINN. Does this only affect the Lite version or the Desktop as well?

We have been investigating this - I think I saw that there was a fix being readied.

Well, if you can shutdown without a kernel panic, you're probably okay. My 3B+ system with Raspbian Desktop that boots from an SD card can shutdown clean (no kernel panic). But others have reported having the issue while booting from SD card, so it's not a USB boot issue after all. I ran into the problem on my SSD booted Raspbian Lite Pi3B, and I haven't tested that system with the Desktop OS (yet). Going back to the mid August stable firmware fixed it for me.

I can shutdown all right.

I had some issues, posted in a new thread.
