That's ksize(invalid_address) -- when the address belongs to an
!PageSlab page.

Why is the kernel called -git13-i486-1mn (the -1mn part)?

Is this a pure vanilla kernel or do you have additional patches

Please send us the entire oops log (including the registers contents,
stack backtrace, "Code:" thing, et al.) -- it's *impossible* to debug
this case, otherwise.
