Upon further inspection, I've found a dmesg regression:

Oct 25 04:01:40 riscv64 kernel: faux_driver regulatory: Direct firmware load for regulatory.db failed with error -2

Unfortunately, the bisect fails to boot on the very last step. But it's either commit "fs: stop sharing fs_struct between init_task 
and pid 1" or commit "fs: add umh argument to struct kernel_clone_args".

Note that in the commit message of "fs: let idle threads share init_fs" it states "Note that kernels before 7.3 need a different 
backport.". I'm guessing all the fs: patches from Christian Brauner should be dropped.
