sysctl_net_inet_tcp_ident panic

[John Klos <john%ziaspace.com@localhost>]

Hi,

I have an amd64 system running netbsd-6 from 2-September-2013. Today, 
while a few machines were scp'ing, this happened:


uvm_fault(0xfffffe80c01971d0, 0x0, 1) -> e
fatal page fault in supervisor mode
trap type 6 code 0 rip ffffffff804a9fbf cs 8 rflags 10246 cr2  44 cpl 0 
rsp ffff8001229c8960
panic: trap

dumping to dev 0,1 offset 212671
dump succeeded


rebooting...


Strangely, it took a while for the system to come up afterwards (I wasn't 
there, and the filesystem is journaled), but eventually it did.

Any ideas?

Thanks,
John
