Using
modunload
While the
nxge
Port Is
Running, Could Cause a System Panic (CR
6551509)
This issue is resolved for servers running the Solaris 10 5/08 OS and later. If you are
running Solaris 10 8/07, you can fix this issue with patch ID 127127-11 or later.
If you run the
modunload
command on the
nxge
driver while it is running, the
system could panic. Due to an issue in the
nxge
driver, it is possible, though very
unlikely, that the
nxge
driver could cause a panic during a system reboot. This panic
occurs if the system is still transferring substantial amounts of network data over an
nxge
interface while the system is shutting down. It is very unlikely that this
condition will occur in normal circumstances.

The server might panic in
nxge_start
when
the
dupb
fails.
If Jumbo Frames are enabled, the system might
panic as a result of a NULL pointer reference.
This scenario is only possible when frame sizes
are larger than 4076. Jumbo Frames with MTU=
9194 do not experience this problem.
Note - This scenario is rare, and only occurs with
frame sizes larger than 4076.
Note - Fixed in the Solaris 10 5/08 OS (and
later) and in the Solaris 10 8/07 OS with patch
ID 127127-11 or later installed.
Disable the use of Jumbo Frames, but be aware
that doing so impacts system performance. You
should only apply the workarounds if your
server is experiencing this problem. For details
on this workaround, see
.
You can also upgrade the OS or install the patch
to avoid encountering this issue.

XAUI interfaces might not be disabled when
they should be disabled.
Normally, when a CPU network interface unit
(NIU) is disabled (either through POST detected
faults or manually), the corresponding XAUI
interface (if one is installed) should also be
disabled, but that does not happen.
Note - Fixed in System Firmware 7.1.6.d or
later.
You can also update the System Firmware to the
latest version to avoid encountering this issue.

Jumbo does not work for packets larger than
8144 bytes when bcopy is forced.
Note - Fixed in the Solaris 10 5/08 OS (and
later) and in the Solaris 10 8/07 OS with patch
ID 127127-11 or later installed.
You can also upgrade the OS or install the patch
to avoid encountering this issue.
