  I poked around in the boot partition. The kernel is ancient!
  Linux version 3.18.71-perf-gaf770dc

    The oldest supported kernel is 5.10 and that loses support in December. That's wild they are using a 3.X kernel

    You'd be surprised how many things you use daily that people still backport the bare minimum to clig to 2.4.x forever

    Yeah I've seen plenty of kernels that start with a 2 with no forward path possible due to "we don't know how to get our driver working anymore"

    I really hope those don't have access to any networks.

    good chance the linux running in your high end phone's modem runs 2.x kernel.
    i dont deal with that anymorrle, but last one I saw with 2.x was the pixel 6 pro.

    Just check, my 2YO phone runs kernel 6.6, not latest but i think good enough for production.
    Edited: I misunderstood what you mean, you were talking about the modem subsystem, sorry.

    I don't think you misunderstood, I think they're talking out their arse. Modems don't run Linux, they run RTOS operating systems. ShannonOS in the case of the Pixel 6 with a exynos modem

    I was working with a Telit 5G modem recently, and it runs OpenWrt. I was flabbergasted when I saw that.

    Plenty of cellular modems run Linux.

    I'll be honest I wasn't considering off the shelf modem modules in my statement. I was talking about your typical cellphone modem made by Samsung, Qualcomm, mediatek. I'm sure there's some basic options and older broadcomm modems and stuff that still run Linux, but most people's devices don't have those
    306bobby · 1789680075 · focus · HN ↗
    The pixel 6 pro runs ShannonOS an RTOS system, it's an exynos modem

    To be fair if you could SLTS support by CIP (which is designed for things like this) you have 4.19 at least still maintained. 4.4 might still be too but I'd have to check
