Bug#630104: [kfreebsd] pstree -a: /proc/19/cmdline: Bad address

[Jonathan Nieder <jrnieder@gmail.com>]

Package: kfreebsd-8
Version: 8.2-1.1

Hi,

Typical kfreebsd-amd64 experimental system, kernel =
kfreebsd-image-8.2-1-amd64 8.2-1.1.  When I try to run
"pstree -a", I get:

	$ pstree -a
	/proc/19/cmdline: Bad address

Indeed:

	$ ps 19
	  PID TTY        STAT    TIME COMMAND
	   19 ?          S+      0:00 [flowcleaner]
	$ cat /proc/19/cmdline
	cat: /proc/19/cmdline: Bad address

By contrast, getting the commandline from ordinary processes
works okay:

	$ cat -A /proc/$$/cmdline; echo
	-bash^@

Known problem?

$ mount | grep proc
linprocfs on /proc (linprocfs, local)
linprocfs on /proc (linprocfs, local, noexec, nosuid)
