>Originator:     Heikki Suonsivu
>Release:        FreeBSD 2.2-CURRENT i386
>Organization:
Clinet, Espoo, Finland
>Environment:

One Pentium with one 8 port cy board (plus couple of two-port
ethernet boards and arnet synch serial board).  The machine is used
as a router, with couple of dialin lines and couple of direct lines
connected to whatever weird stuff we have in our computer room 
(UPS alarm, temperature alarm, telephone switches)

One 486-100 with two 8 port cy boards.

>Description:

Processes get hung on ports, unkillable.   On the latter machine
this happened with dialup login account:

1271     29565  0.0  0.1   192   12  c7- IEs+ -          0:00.00  (rlogin.shell)
1271     29694  0.0  1.7   192  224  c7- IE+  -          0:00.00  (rlogin.shell)

On Pentium machine similar hang occured when trying to kermit into a
telephone switch connected to one of the ports of the cyclades board.

>How-To-Repeat:

I do not know yet.  On 486-100 this happened first time after
70 days of uptime, on Pentium after less uptime.  This does not 
seem to happen often, so it is a bit hard to track down.
