PROBLEM DESCRIPTION:
Due to a bug in the AXQ ASIC which resides on the System Expander
Board of the F15K, a Solaris panic can occur if too many outstanding
noncacheable Programmed I/O transactions are awaiting service. A
transaction may then timeout in the Schizo ASIC causing the Solaris
device driver(s) to panic. An example panic:

This issue has been root caused to a bug in the AXQ ASIC. An updated
AXQ is planned for a future release, however this software workaround
is permanent in Solaris, so the AXQ revision present in the system is
irrelevant.
The likelihood of encountering the failure is low, but because of the
impact if encountered, implementation of the corrective action is
recommended for all Gold and Platinum customers.
IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)
---
---
| X | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
---
---
| | REACTIVE (As Required)
---
CORRECTIVE ACTION:
The following recommendation is provided as a guideline for authorized
Enterprise Services Field Representatives who may encounter the above
mentioned problem.
Please perform the following guideline as needed:
Install Solaris 8 patches 108528 (or newer) and 110838 (or
newer) to affected Sun Fire 15K domains.
NOTE: If the customer is participating in the Sun Fire 15K
DR Beta Program, the DR specific kernel already contains
an integrated software workaround.
COMMENTS:
None
--------------------------------------------------------------------------
Implementation Footnote:
i) In case of MANDATORY FINs, Enterprise Services will attempt to
contact all affected customers to recommend implementation of
the FIN.
ii) For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical
support teams will recommend implementation of the FIN (to their
respective accounts), at the convenience of the customer.
iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the
need arises.
