I solved this one by applying this:

Wow! Unwinding is noticeably faster than libunwind! The trace is almost
perfect. I think I found only one unresolved symbol (it's always the
same one, maybe I screwed up the compilation):
0.01% ls [kernel.kallsyms] [k] do_raw_read_unlock

sys_readlinkat
sys_readlink
system_call
__GI___readlink
get_link_name
gobble_file

Is this going into mainline soon?
