Re: Repeatable panic on amd64 (-current as of Dec 22nd)

My D525 based Atom system can be repeatably panic'ed by "netstat -an" as root after doing "telnet fqdn 80" as a normal user (where fqdn is the FQDN of the local system). It appears that there's a failed assert (so it's just a plain 'ol crash with a non-debug kernel):

panic: kernel diagnostic assertion "cred2 != NULL" failed: file "/data/nbu/source/netbsd/src/sys/kern/kern_auth.c", line 568

The system fails to provide a traceback, and the serial console is unresponsive after the panic, so not sure it it dropped to DDB on the VGA console or not. Please advise on what additional information to provide (or to send-pr this). A dmesg from the system is pasted below.

I should be more precise there...I'm not connecting to the FQDN of the local machine, but of the DD-WRT router in front of it, which NAT's the packets to the local system. If I do some other "normal" telnet (like to the actual FQDN of the machine), I haven't been able to repeat the failure.

I didn't check a packet capture to see what is unique about the NAT's packets, but not sure if that's relevant or not.
