I haven't fixed it yet, but the modules should get installed despite the=20
SSL signing errors.  The kernel should be able to load the modules=20
unless it is built with the CONFIG_MODULE_SIG_FORCE option, or the=20
module.sig_enforce kernel command line parameter is set, or secure boot=20
is enabled.

Note that due to a recently fixed kernel memory corruption bug, be sure=20
to use the latest sources at the time of this email, or later.

Cheers,
Ian
