Patch Name:  PHNE_1206

Patch Description:  Bad value in the length field of IP option could panic.

    This happens when the system tries to send back an ICMP error message.
    Also, the ICMP error message was not correctly built.

    This was an interrupt type 18, Data memory protection fault on
    the interrupt stack.  The stack trace looks like:
                        panic+0x0028
                        interrupt+0x07e4
                        ip_insertoptions+0x01b8
                        ip_output+0x0080
                        icmp_send+0x98
                        icmp_reflect+0x0118
                        icmp_error+0x0304
                        ip_dooptions
                        pintr+0x02d4
                        netisr+0x00a8

After getting the patch onto your machine, unshar the patch

To install this patch do the following:
1) Run the update program (Note: you must be root to update a system).
2) Once in the update "Main Menu" move the highlighted line to "Change
   Source or Destination ->" and press "Return" or "Select Item".
3) Make sure the highlighted item in the "Change Source or Destination"
   window is "From Tape Device to Local System ...", then press "Return"
   or "Select Item".
4) You should now be in the "From Tape Device to Local System" window.
   Change the "Source:  /dev/rmt/0m" to "Source: PHNE_1206.updt" assuming
   you are in the directory where PHNE_1206.updt has been placed.  In some
   versions, you may need to enter the absolute path name.  In others, the
   default "/dev/rmt/0m" may not appear in the field as default.
5) Press "Done".
6) Move to the "Select All Filesets on Source Media" line and press "Return".

The customized script that update runs will move the original software
to /system/PHNE_1206/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended
that you move the PHNE_1206.text file to /system/PHNE_1206 to be
retained for future reference.

If you wish to put this patch on a magnetic tape and update from the
