My MSI B450 Tomahawk is exhibiting this bug now that I've updated the firmware 
to the latest beta BIOS with AGESA 1.1.0.0 patch D.

There appears to be a regression with the filesystem NLS modules. I cannot load 
any of them. They all produce:

modprobe: ERROR: could not insert 'nls_cp437': Invalid argument

The system journal reports:

Jan 08 02:04:56 mrgency kernel: BPF:No data
Jan 08 02:04:56 mrgency kernel: failed to validate module [nls_cp437] BTF: -22

As a result, I cannot mount vfat filesystems with the usual CP437 default. Or 
any other code page, for that matter.
