Hi Christoph, Sorry for the delay, it was Finland's Independence Day so I was offline for a long weekend.

But this makes me wonder is it sensible to randomly install a set of .ko files and drop the rest, like Debian's installer apparently does? The dependency for drivers is pretty well documented in Kconfig files, thanks to build testers testing with random configurations, but if the installer omits all that there will be problems just like you are experiencing. So for me MODULE_SOFTDEP() feels just like a band aid and not a robust solution. Though I am happy to take your MODULE_SOFTDEP() patch, just wondering if there is a better way to solve this. For example net/mac80211 (the 802.11 stack) has a lot of crypto dependencies: select CRYPTO select CRYPTO_LIB_ARC4 select CRYPTO_AES select CRYPTO_CCM select CRYPTO_GCM select CRYPTO_CMAC select CRC32 And it's not using MODULE_SOFTDEP() at all. > but if you have a good idea to make the error reporting more useful that > would be appreciated as well. I'll send a patch to improve the error messages in this case. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
