This means the same processor which held the simple lock at 0xc032c5c0
tried to lock it again. Because simple lock code is written in asm and
without a stack frame, it didn't show up in the stack trace. Look up
0xc032c5c0 in the kernel's name list, it should give you a good clue
on what went wrong.
