Long past due for retirement, the Linux 7.0 kernel has removed the obsolete Mwave driver for the 3780i ACP Modem found in some Pentium II era IBM ThinkPads from the 1990s.

The Mwave Linux driver was for the 3780i ACP Modem found in some ThinkPads. Found on the likes of the IBM ThinkPad 600E, 600, and 770 these modems allowed 56K connectivity. IBM wrote the Mwave kernel driver and the associated user-space software for it back in the 1990s.

On the contrary, whoever is running current software on a 90s ThinkPad will be over the moon to have an excuse to patch the kernel

I would assume people running a modern kernel on an orignal 32-bit first generation pentium machine don’t need such an excuse as they have to do in constantly already…
