yes you can use mdev-3905 config and error log, that's the original one (the only change is password, i put ##### )
i'm using mysqld_multi start
and it starts normally with skip-pbxt option inside my.cnf file
here is ps ax | grep where you can see it running normally with skip-pbxt option
[root@SPADIM-DELL ~]# ps ax | grep mysql
