This bit here:

    [    2.693861] Loading module verification certificates 
    [    2.698920] X.509: Cert 8b7774b08bc4ee9637073434c10f0823f6fbe523 is not 
yet valid 
    [    2.706444] MODSIGN: Problem loading in-kernel X.509 certificate (-129) 

After those lines, you have indeed managed to load some modules:

    [   35.218540] Modules linked in: kvm(F+) microcode(F+) i2c_nforce2(F) 
edac_core(F) k8temp(F) shpchp(F) serio_raw(F) pcspkr(F) xfs(F) libcrc32c(F) 
sd_mod(F) crc_t10dif(F) sr_mod(F) cdrom(F) mptsas(F) radeon(F) i2c_algo_bit(F) 
scsi_transport_sas(F) drm_kms_helper(F) mptscsih(F) ttm(F) drm(F) mptbase(F) 
i2c_core(F) usb_storage(F) dm_mirror(F) dm_region_hash(F) dm_log(F) dm_mod(F) 

Each of which appears to have incurred the:

    [   34.917174] Request for unknown module key 'Magrathea: Glacier signing 
key: 8b7774b08bc4ee9637073434c10f0823f6fbe523' err -11 

error.

So that seems to be what I thought it was, but it doesn't seem to have been a
problem for most modules.
