   BugID: 4830665

Issue Description: 

A Crystal-2A card (or other PCI adapter cards) in Slot 1 of the hsPCI I/O Board
which uses a 5.0v PCI cassette may not be recognized upon boot or may unexpectedly fail
to initialize.  This issue causes devices attached to the Crystal-2A (or other PCI
adapter cards) to lose availability.

There is also a potential for the loss of previously configured NVRAM settings on
the Crystal2A which would cause it to revert back to the default NVRAM settings.

The affected configuration is the following:

   - hsPCI I/O Board with a 5.0v PCI Cassette in Slot 1

Note:  The issue has been only been observed with the Crystal-2A PCI Dual FC
Network Adapter, however it is believed that other adapter cards might also be
affected.  Exactly what other cards might be affected is not known.


Symptoms
--------

The symptoms of this issue are improper initialization of devices and lack
of recognition of devices upon boot up.

It is unpredictable.  On occasion some initializations and/or boot sequences
will work but on other occasions initializations and boot up will fail.

Possible error messages would include:

   Mar 11 ... [ID 702911 user.error] RECONFIGURING IO7S1
   Mar 11 ... pcihp: [ID 709949 kern.notice] NOTICE: pcihp (pcisch2): 
              card is inserted in the slot e07b1slot1 (pci dev 1)
   Mar 11 ... [ID 398841 kern.notice] NOTICE: vca1: Timed out
              waiting for POST, attempting to reset device.
   Mar 11 ... [ID 586887 kern.notice] NOTICE: vca1: Resetting board...
   Mar 11 ... [ID 725567 kern.warning] WARNING: vca1: Timeout
              waiting for POST.  Device hung?
   Mar 11 ... [ID 618048 kern.warning] WARNING: vca1: Unable to initialize device!
   Mar 11 ... pcihp: [ID 250731 kern.warning] WARNING: pcihp 
              (pcisch2): failed to attach one or more drivers for the card
              in the slot e07b1slot1

If using the cfgadm(1M) command, output would show:

   pcisch2:e07b1slot1  disconnected  unconfigured  unknown  C5V0


Final determination of this issue can be made by moving the cassette with
the Crystal-2A card from Slot 1 to Slot 3. If the devices are now recognized
and initialized properly when in Slot 3 then this issue has been encountered.


Root Cause
----------

This issue was root caused to a grounding defect with Slot 1 of the hsPCI I/O
Board.  However, it was decided to address the grounding by modifying the 5.0v
cassette.

Slot 1 on the hsPCI I/O Board does not does not follow the PCI Bus specification.
The hsPCI slot 1 is fixed at 5 volts and 33Mhz.  The PCI Bus specification section
7.5.1 states "Expansion boards and bus segments not capable of operation in 66Mhz
mode must connect the M66EN pin to ground.".  This pin is not connected to ground
in this slot on the hsPCI board as it should be, but since the 5.0v cassette is
only used on 33Mhz segments, the 5.0v cassette has been modified to ground this pin
as a solution to the hsPCI board defect.

The 501-5600-09 (or above) addresses the issue by removing a capacitor
on the 5.0v cassette and replacing it with a resistor to tie the required
signal to ground.

Special Considerations: 

This FCO will have a timezone phased release based on material
readiness as follows:

   All Americas    Nov 05, 2004
   EMEA            Nov 15, 2004
   APAC/Japan      Nov 30, 2004

The above dates represent when each timezone has determined
they will be materially ready to support this FCO.

Corrective Action: 

If this issue is encountered, upon failure replace the following:

   - replace 501-5600-08 (or lower) with 501-5600-09 (or above)
