kldload: can't load acpi_video: module already loaded or in kernel

https://github.com/helloSystem/ISO/commit/b158ece4249c961d26298a372664b7832f69ce4d#diff-ed559147af536020ba4ab28e08b4965092f7c5266c97d2c6e64c62ab10af4c4fR59-R68

Thanks @grahamperrin. Do you know what the solution would be?

grahamperrin commented 1 year ago

If the module is already loaded or in kernel, then do the linked parts of overlays/uzip/hello/files/etc/rc.d/load_acpi (loading the module) make sense?

probonopd commented 1 year ago

The question is, how can we find out whether the module is already loaded (and why) or in the kernel?

grahamperrin commented 1 year ago

(and why)

Try debug.verbose_sysinit=1 in loader.conf(5).

Postscript: that'll not work in distributions that are based on STABLE or RELEASE.

https://github.com/freebsd/freebsd-src/commit/be352d20d5198f55ed91c3805d5e7272b3f636a7 … turned off in stable branches …, so no VERBOSE_SYSINIT in releng/13.0 at https://github.com/freebsd/freebsd-src/blob/releng/13.0/sys/amd64/conf/GENERIC, and so on.

I don't see this with an installation of experimental-14.0-0.8.0_0H77:
