Please reproduce and try "area -m 0x0007ffffffffff", replacing 0x0007ffffffffff with the user-mapped address. Then "team 0xff", replacing 0xff with the owner from the area command output. And then

This should help to identify the user memory being passed to the kernel, but I suspect it's a user stack.

Why don't we get a full backtrace here?

@korli: I ran all the presumably-loaded kernel images through nm | haikuc++filt with the guarded heap enabled, and got no crashes whatsoever. So why are we getting read faults on demangling here?
