At some point between 20 Jun and (by my best guest) 22 Jun there has been
a problem introduced somewhere... How much more vague can you get? :)...
File creation works fine, but attempting to rm causes a panic.
config and dmesg (of a non-panicking kernel) are attached, panic message
and gdb stuff below... Hope it's enough info to get a fix in the works!
Fatal trap 12: page fault while in kernel mode
