So far here is a stack traceback of the panic.

panic("m_copym")  // Helpful 'eh ?

panic
m_copym+0x4e
ip_output+0x5a0
ip_mforward+0x21b
ip_mforward+0x1b0
ipintr+0x1f6
spl0+0x38
comintr+0x3b
Xcom1+0x52

It looks like the panic in m_copym with a test for a NULL mbuf ptr. I can
reproduce it easily- just need be be careful not to panic when in X

Any ideas/clues ?
