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.

https://www.telit.com/devices/fe990bxx/ - "High-performance quad-core CPU and Linux OpenWRT OS, ideal for router development without an external CPU"

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

The pixel 6 pro runs ShannonOS an RTOS system, it's an exynos modem
