TABLE 6
CR ID Description
6545143 There is a low probability that a system panic
can occur during trap processing of a TLB miss
for a user stack address. The problem can
occur if the user stack is unmapped
concurrently with the user process executing a
flush windows trap (ta 3). The panic message
will contain the following string:
bad kernel MMU trap at TL 2
6545685 If the system has detected Correctable
MemoryErrors (CE) at power-on self-test
(POST), the domains might incorrectly
degrade 4 or 8 DIMMs.
6546188 The system panics when running hot-plug
(cfgadm) and DR operations (addboard and
deleteboard)on the following cards:
• X4447A-Z, PCI-e Quad-port Gigabit Ethernet
Adapter UTP
• X1027A-Z1, PCI-e Dual 10 Gigabit Ethernet
Fiber XFP Low profile Adapter
6551356 The system panics when running hot-plug
(cfgadm) to configure a previously
unconfigured card. The message "WARNING:
PCI Expansion ROM is not accessible" will be
seen on the console shortly before the system
panic. The following cards are affected by
this defect:
• X4447A-Z, PCI-e Quad-port Gigabit Ethernet
Adapter UTP
• X1027A-Z1, PCI-e Dual 10 Gigabit Ethernet
Fiber XFP Low profile Adapter
6556742 The system panics when DiskSuite cannot
read the metadb during DR. This bug affects
the following cards:
• SG-XPCIE2FC-QF4, 4Gb PCI-e Dual-Port
Fibre Channel HBA
• SG-XPCIE1FC-QF4, 4Gb PCI-e Single-Port
Fibre Channel HBA
• SG-XPCI2FC-QF4, 4Gb PCI-X Dual-Port
Fibre Channel HBA
• SG-XPCI1FC-QF4, 4Gb PCI-X Single-Port
Fibre Channel HBA

Workaround
There is no workaround.
Increase the memory patrol timeout values used
via the following setting in /etc/system and
reboot the system:
set mc-opl:mc_max_rewrite_loop =
20000
There is no workaround.
Note - Do not use cfgadm -c unconfigure
to disconnect the I/O card. Use cfgadm -c
disconnect to completely remove the card.
After waiting at least 10 seconds, the card
might be configured back into the domain
using the cfgadm -c configure command.
Panic can be avoided when a duplicated copy of
the metadb is accessible via another Host Bus
Adaptor.
