Sun Fire[TM] E25K, E20K, E15K, E12K : BERR panic events off PCI-X/PCI Quad 
Gigaswift ethernet card installed on schizo based hsPCI slot
For example, the BERR panic event as reproduced in a Solaris[TM] 8 domain environment resident in a Sun Fire 15000 platform loaded with the Solaris 8 KU, 117350-39 & ce driver patch, 111883-34 ( which deploys CE Ethernet Driver v1.154 ) :

/IO14/C5V0 PCI 476 B 33 33 1,0 ok pci-pci8086,537c.7/network (netw+ pci-bridge 
/IO14/C5V0 PCI 476 B 33 33 0,0 ok network-pci100b,35.30 SUNW,pci-x-qge 
/IO14/C5V0 PCI 476 B 33 33 1,0 ok network-pci100b,35.30 SUNW,pci-x-qge 
/IO14/C5V0 PCI 476 B 33 33 2,0 ok network-pci100b,35.30 SUNW,pci-x-qge 
/IO14/C5V0 PCI 476 B 33 33 3,0 ok network-pci100b,35.30 SUNW,pci-x-qge 

PCI-X/PCI Quad Gigaswift ethernet card ( X4445 ) deployed at IO14 slot C5V0.

The BERR panic event reproduced in the above domain OS environment is reported as follows :

WARNING: [AFT1] Bus Error (BERR) Event detected by CPU515 Privileged Data Access at TL=0, errID 0x00000479.9d38b088
AFSR 0x00100800.00000000 AFAR 0x00000479.00200000
Fault_PC 0x10035eb4

panic[cpu515]/thread=2a10027dd20: [AFT1] errID 0x00000479.9d38b088 BERR Error(s)

where the AFAR value reported off the above AFT1 event is isolated to the following I/O location :

redxl> parse pa 479.00200000
16 GB Nasm slice 30 = 0x1E, 4GB quadrant 1: IOBus IO14/P0/B1 (14.1.0.1)
Offset = 00200000

=> which translates to the I/O location housing the qge (X4445) card ( IO14 slot C5V0 ).

Under conditions as described by the domain OS environment above, there's very little yield in addressing the BERR panic condition via replacing the PCI-X/PCI Quad Gigaswift ethernet card(s) ( X4445 ) flagged by the BERR panic event. 

Instead, the affected site should explore the following course of action to workaround the BERR panic condition :

Replace the PCI-X/PCI Quad Gigaswift ethernet card(s) ( X4445 , QGE-X ) with the X4444, QGE PCI Quad Gigaswift ethernet card(s).

Efforts to replicate the same BERR panic condition have not been successful in the same domain OS environment described above when the X4445 PCI-X/PCI Quad Gigaswift ethernet card is replaced by a X4444 PCI Quad Gigaswift ethernet card.

The test results available thus far point to the fact that the X4444 card can be used a workaround solution to the BERR panic condition encountered when the X4445 card is deployed. Please bear in mind that there is no RoHS compliant version of the X4444.
