Yes, it's in ddb. There is a trace in the previous message also, but here it is
a new one. This happens everytime when ssh'ing to something, maybe in other
cases also. The previous one was within a cvs update.
After the ssh command is entered, the console freezes, but I can still receive
the replies from ping for 2 to 4 minutes. Then, it panics.
Hope this helps.
Thank you.
