Description

Solaris 10 and Solaris 11 systems with bge(7D) chip type 5718 and kernel Patch 142909-17/142910-17 (or later) may panic if 'dladm show-linkprop' (dladm(1M)) and 'kstat -m bge' (kstat(1M)) commands are issued simultaneously.

Occurrence

This issue can occur for all systems with bge(7D) chip type 5718 that have the following releases:

SPARC Platform

• Solaris 10 with patch 142909-17 (or later) and without patch 147161-04
• Solaris 11 without SRU 2011.11 SRU 06

x86 Platform

• Solaris 10 with patch 142910-17 (or later) and without patch 147162-04
• Solaris 11 without SRU 2011.11 SRU 06

Notes:

1. Solaris 8 and Solaris 9 are not impacted by this issue.
2. Solaris 11 Express will not be evaluated regarding this issue.
3. All Systems running Solaris 10 and Solaris 11 with bge interface chip type 5718 are affected by this issue.
4. This issue only impacts systems that are using the bge driver for the 5718 chipset based NICs.

To determine if a system is equipped with the 5718 chipset based NIC, the following command can be used:

# kstat -c net -m bge -n chipid | grep chip_type
  chip_type                       5718
  chip_type                       5718
  chip_type                       5718
  chip_type                       5718

Symptoms

Should this issue occur, the system will panic with a stack trace similar to the following:

panic on CPU 7

Workaround

To avoid this issue, do not run "dladm show-linkprop" and "kstat -m bge" commands simultaneously on a system with bge interfaces chip type 5718.

This issue is addressed in the following releases:

SPARC Platform

• Solaris 10 with patch 147161-04 or later
• Solaris 11 SRU 2011.11 SRU 06 or later

x86 Platform

• Solaris 10 with patch 147162-04 or later
• Solaris 11 SRU 2011.11 SRU 06 or later

Patches

<SUNPATCH:147161-04>
<SUNPATCH:147162-04>

History

12-Mar-2012: Date of Resolved Release
30-Jan-2013: Maintenance update; no change in content

This is a regression issue caused by putback to CR6226441.
