Kernel Too Old

Postby cbcs01 » Tue Aug 16, 2016 4:02 pm

I have been running a TonidoPlug 2 on ArchLinux for a number of years. The last version of the Kernel using pacman -Syu was 3.1.10-35. Yesterday, I applied the pacman -Syu updates and the system responded with "Kernel too old" after one of the updates (I think it was glibc as I managed to update another TonidoPlug2 with all of the updates that didn't include glibc). At this point, the system is still running, but I cannot connect to it. It runs as a headless system so the connectivity options are limited. Any ideas on how to recover this system? It is running on a SATA drive.
Thanks.

In that time you missed, you need to move to linux-armv5 or linux-kirkwood

Why didn't pacman -Syu automatically update my kernel? I run it every day and apply any updates.
Second, can I switch to the kirkwood kernel on another TonidoPlug2 without bricking it?

Because you had linux* installed from way back when, it won't magically move you to a different kernel, since that was split into multiple different packages for different machines.

ARM isn't x86. You don't always have one grand unified kernel.

I have been running ArchLinux for over 4 years on a number of ARM versions, and have been quite impressed by the quality of the support, which is why I was surprised when the update make the Tonido unusable. Other ArchLinux versions, e.g. RaspberryPi and BeagleBone Black, upgraded kernels without any issues. A warning about the incompatibility would have been very much appreciated, rather than having the result unusable.

All of those other platforms never started on the package "linux", and this is why they never had this problem.

So how is the issue fixed? Do I have to do a fresh install?

You can manually extract the linux-kirkwood package and place /boot contents as necessary, but it should not require a fresh install.

WarheadsSE, that worked perfectly. If it's not too long of a response, could you explain what happened.

High-speed summmary:
- once, ALARM was armv5te, kirkwood only (PogoPlug E02)
- back then, "linux" was the only package
- Add many architectures, and many other armv5te boards
- kernel packages split
- Assuming that "linux" should be replaced by "linux-kirkwood" is erroneous for everything not kirkwood
- "linux" languishes at 3.x
- linux-armv5, linux-kirkwood, etc continue to roll with updates
- unmaintained systems eventually get tripped up.
