OpenBSD 3.3 wedged using sysctl

Hi,

Had couple of solid wedges happen the other day.

A clean install of OpenBSD 3.3 setup as a RAS server using pppd and PAP auth. I've appended the dmesg output below.

Nothing in syslog about it and there was no core dump or panic that I could see, just a frozen console. Couldn't ping the box either.

The server uses an old ISA cyclades card which seems to be setup correctly. We set up pppd to use proxyarp and issue IP addresses from the ethernet network range.

During trouble shooting on the initial install, I was checking that the box was set up for routing with "sysctl -a | grep forward" and it wedged. It was repeatable at the time but I'm not sure if it is now. We switched to userland PPP as pppd was not playing the game properly, only the first person on would get a route (even though ifconf showed the ppp interface was configured) and it wasn't adding an entry in utmp ("who" didn't show the user although "last" did).

I'm not too concerned about it but it was really unusual in my experience with OpenBSD so I thought it worth noting.

ciao
