Re: Kernel panic from network traffic
Hi, It's probably due to my recent change to refcnt. I'm investigating that defect.

Re: Kernel panic from network traffic
Hi, I just fixed one bug related to refcnt. The fix may shut up the panic. Could you try again with a latest kernel?

Re: Change in xsrc and src tree structure?
The old X11R6 stuff was removed.

What is now the version of native xorg-server? I am now on NetBSD-current (7.99.15) with modular (pkgsrc) xorg, therefore didn't build the xsrc part.

Hello fellow moron :) I have a general question: I see some comments around unifying route caches, but in this particular case it seems related to ipv6. Is this an ipv6 problem or a general problem? I have a -current machine and it's not likely to encounter this particular scenario (sorry, heh), but wondering anyway. Thanks! Andy

I have a -current machine and it's not likely to encounter this particular scenario (sorry, heh), but wondering anyway. I'm not sure of what kind of flood of traffic was seen at the -current box (tcpdump wasn't being helpful) but I kind of doubt it was IPv6 only. But who knows? My guess is that there is IPv6 routing traffic mixed in with a whole lot of garbage from my switch. -- Hisashi T Fujinaka - ht...@twofifty.com BSEE + BSChem + BAEnglish + MSCS + $2.50 = coffee
