Re: Net/OpenBSD local reboot

I have limited resources to play around with, but on my OpenBSD.current PPP system, one of:
ping -s2955 1.2.3.4 or ping -s1455 1.2.3.4 causes kernel panic
It's my guess that this is due to a magic MTU of 1500 which the packet just barely exceeds, resulting in only three bytes of data (one octet) in the last frag.
For what it's worth, on a NetBSD/sparc machine running code supped in the AM of July 8th, I don't get any problem from those commands, even though the Ethernet MTU is also 1500. So either this version of NetBSD is immune or it's something ppp-specific. (I don't currently have any easy way to fire up ppp; that will have to wait until I get home.)
I have second hand confirmation that this problem exists under netbsd as well,
Without more specifics (eg, what version of NetBSD? was it necessary to use ppp to get the panic? what was the panic?), it's hard to tell. der Mouse mouse () rodents montreal qc ca 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
