If the system has a high performance HBA and this PCI card is placed on the same PCI Bus with any other PCI card which causes the Schizo chip to attempt a 64-bit PIO, a system panic would most likely result.  The problem will not occur if the High performance HBA card is installed alone on a PCI Bus.

UltraSparc-III platforms utilizing the Schizo 2.1 or 2.2 ASIC may experience panics due to address parity errors on the PCI Bus. The problem has been seen on the Sun Fire 280R with the Emulex FC HBA card in combination with a PGX32 card installed on the same PCI Bus, and also seen on the Sun Fire V480/V880 with the Jasper 320 PCI-X - Dual Ultra-320.

This condition occurs when a card on the PCI Bus detects a 64-bit parity address error on the PCI Bus while another card on the same PCI Bus is performing a 64-bit PIO.

The following error messages are displayed prior to a system panic:

WARNING: pcisch-0: PCI fault log start:
PCI SERR
PCI error ocurred on device #6
dwordmask=0 bytemask=0
PCI primary error (0):
pcisch-0: PCI secondary error (0):
pcisch-0: PBM AFAR 0.00000000:
pcisch-0: PCI config space error status (4280):
signalled system error.
pcisch-0: PCI fault log end.
panic[cpu1]/thread=2a10000bd40: pcisch-0: PCI bus 2 error(s)!

This problem can theoretically occur with other cards which use PIO.  In one particular case, the problem occurs when a device (Emulex) performs a legal check on the 64-bit extension parity while the Schizo chip is performing 64-bit PIO to the PGX32 board. The Emulex board detects an address parity error, and signals this via SERR. This leads to a system panic.

Engineering has determined that the parity errors and subsequent panics are occurring because the Schizo chip does not drive the upper address bits during the address phase of a 64-bit PIO transaction. The address bits default to all one's, which is incorrect parity. The HBA card detects this incorrect parity and issues an SERR. A panic follows.

The solutions outlined below depends on the type of graphics card ( PGX32 or PGX64 ) being installed.

Solution 1:

If using the PGX32 graphic card, install Patch-ID#109154-10.

Solution 2:

If using the PGX64 graphics card,

1. Install Patch-ID#108606-18

2. Create the config file: /platform/sun4u/kernel/drv/m64.conf add the following entry: disableLongPIO=1;

3. At 'ok' prompt, modify OBP parameter 'output-device' using; setenv output-device screen:r1280x1024x76x24

4. Shutdown the system, install the PGX64 card, and then reboot to install the new PGX m64 driver.

Solution 3:

If the system is either a V480 system,

1: If the graphics card installed is PGX32, follow solution 1

2: If the graphics card installed is PGX64, follow solution 2

3: If the graphics card is either XVR100/XVR500 upgrade motherboard to 501-6780

Solution 4:

If the system is either a V880 system,

1: If the graphics card installed is PGX32, follow solution 1

2: If the graphics card installed is PGX64, follow solution 2

3: If the graphics card is either XVR100/XVR500 upgrade motherboard to 501-6771

• Updated FIN to include V480 server.  I also entered the product list into the correct box in the tool.
