 Can you get a line number for wddone+0x256?
 
 $ gdb ./netbsd.gdb
 (gdb) info line *(wddone+0x256)
 
 Can you also show the full lockdebug info?  It looks like it got
 garbled in the console output.
 
 db> show lock 0x0000000000a97148
 
 This should display two lines of particular interest (with different
 addresses, obviously):
 
 initialized  : 0x0000000000abcdef
 ...
 last locked* : 0x0000000000123456 unlocked : 0x0000000abcd0123
 
 Can you show line numbers for the `initialized' and `last locked'
 addresses?
 
 (gdb) info line *(0x0000000000abcdef)
 (gdb) info line *(0x0000000000123456)
