Hello,
all previously mentioned issues have been addressed in
the meantime:
- The broken initrd support has been fixed upstream in kernel
4.19-rc4.
- The symbol version issue has been fixed upstream in kernel
4.19-rc6.
- The riscv64 kernel config has been modularized as far as
possible and all redundant entries have been removed.
- Headings have been added to the kernel config.
Attached is a new patch, alternatively it is available as a merge
request on salsa as suggested earlier in the discussion:
https://salsa.debian.org/kernel-team/linux/merge_requests/66
The resulting kernel has been successfully tested on a qemu
"virt" board:
