I presume the panic was in the 'return to user' sequence?
Does it now SIGSEGV the program?

Actually, since userspace isn't allowed to change the user %cs - well
not to a value the kernel doesn't verify - all bets are off as to what
happens next.
(putting in the kernel %cs might leave you running user code with
kernel privelege)
