 I've seen the same kind of panics twice now with NetBSD-current 2.99.15 
 from ~20050131. I haven't been able to trigger it with simple FTP tests,
 so I assumed it was related to another problem (see kern/29529).
 
 I have a crash dump of the first panic, if somebody is interested.
 The panic message was something about m_copydata, but I don't have the
 details at hand right now.
 
 
 Hope this helps,
