kernel fails to install modules

[KShots]

Running 'make modules_install' produces this error on gentoo-sources-6.17.9:

Code: Select all

depmod: ERROR: Cycle detected: 8250 -> 8250_base -> 8250
depmod: ERROR: Cycle detected: serial_mctrl_gpio
depmod: ERROR: Found 2 modules in dependency cycles!

Anything I can do to resolve this?

Seems to also be a problem for 6.17.8...

Fixed it - 6.17 does not support compiling 8250 serial drivers as modules. Making it built-in to the kernel resolves this.

Is that inability considered a deliberate change, a reported bug that may be fixed, or is it an unreported defect? I would have expected that if this is not supposed to work, then the Kconfig language should have prevented you from choosing that configuration.

I would also have expected it to have worked - I've had kernels with modular 8250 serials for more than a decade. I suspect it's an unintentional regression that will be fixed in a later update.

[zen_desu]

is it a kernel change or depmod no longer allowing modules with dependency loops?

[KShots]

I'm afraid I can't speak to that - all I can say is that I've been using the 8250 modules as modules for decades, and the last time they worked was with 6.12.58. anything between 6.12.58 and 6.17.8 may or may not act that way...

If this is a regression, could you link to where this was reported, so that affected readers can follow along to track work on a fix?
