Description thulle 2021-07-04 14:02:20 UTC 
When compiling kernel 5.13 with the new CONFIG_MODULE_COMPRESS_ZSTD set to y, genkernel doesn't seem to pick up the kernel modules any more.

At the step ">> Appending modules cpio data ..." it gave a warning about 0 modules found.

Switching to CONFIG_MODULE_COMPRESS_NONE=y it works as intended without warning.
