Title:
Boot fails: failed to validate module [nls_iso8859_1] BTF: -22
Status in linux package in Ubuntu:
Incomplete
Bug description:
I just updated to an unstable kernel build from the kernels team Repo
it´s the 5.11-2.3 package (5.11 RC3)
The mount of /dev/boot fails with a message:
IO charset iso8859-1 not found
this is probably due to the kernel being unable to load the
nls_iso8859-1 module.
I see multiple messages with BPF:No data
and for the nls_iso8859-1 module a message:
failed to validate module [nls_iso8859_1] BTF: -22
this is probably introduced by this patch:
https://lkml.org/lkml/2020/11/6/1143
I don´t undestand what BTF validation is and whether this is an issue
with linux 5.11-rc3 or with how the kernel modules are packaged in
Ubuntu.
My machine is a Renoir (zen2) based Acer Laptop running in UEFI mode, with a
fat32 /boot partition and a ext4 / root partition.
The root partition gets mounted, but once the /boot should be mounted, this
fails with the mentioned error..
Other modules seem to load fine, things like "amdgpu" are already
loaded!
