I hope this repeats....
I was doing an install. Since the security distribution isn't
included on the cd, I ftp'ed it to a local system and after
installing everything else from cdrom, I tried to use the install
program to ftp over the security distribution.
I usually turn prompting off and when I typed 'mget *' without
remembering to turn prompting off, I did what I normall do in that
situation: I hit ^C.
The install script picked up on this and switched me back to
primary virtual console. Ftp was still trying to get my keystrokes
and so was the install program. A few moments of typing later,
the system panic'ed.
Fixed with the rewrite of sysinstall for 2.0.5R
