RELEASE NOTES
1. Patch SG0003318 Release Note
This release note describes patch SG0003318 to IRIX 6.2.
1.1 Supported Hardware Platforms
This patch contains bug fixes for the following machine
types. The software cannot be installed on other
configurations.
o Challenge and Onyx with R4400 processors
o POWER Challenge L/XL & POWER Onyx with R8000 processors
o Challenge/Onyx/POWER Challenge L/XL with R10000
processors
1.2 Supported Software Platforms
This patch contains bug fixes for above systems running IRIX
6.2. The software cannot be installed on other
configurations.
This patch replaces patch SG0001536,SG0002761.
1.3 Bugs Fixed by Patch SG0003318
This patch contains fixes for the following bugs in IRIX
6.2. Bug numbers from Silicon Graphics bug tracking system
are included for reference.
o 590386 Fixed wd95.c code to check for reset interrupt
bit first and ignore other bogus interrupt bits during
reset to avoid errors in figuring out what state of the
chip is in.
1.4 Bugs Fixed by predecessors to Patch SG0003318
o 552731 Code is updated to have the same level of bug
fixes as 6.4.
o 543096 qlinfo and scipinfo updated to handle a BUSY
status on the inquiry command.
o 395687 Under very heavy loads, it was possible for the
SCSI controller to become confused and think that the
input queue had wrapped. This caused it to execute
incorrect commands. When it completed them, they
weren't found on the driver active queues. This caused
the system to panic.
o 397611 Also under very heavy loads, it was possible for
DMA completion for a given command to be done very
slowly, such that it was not complete when another
command became active on the SCSI bus. When this
occurred, the user would see a SCSI timeout, previous
to which activity on the affected SCSI bus would come
to a halt.
1.5 Subsystems Included in Patch SG0003318
This patch release includes these subsystems:
o patchSG0003318.eoe_sw.unix
1.6 Installation Instructions
Because you want to install only the patches for problems
you have encountered, patch software is not installed by
default. After reading the descriptions of the bugs fixed
in this patch (see Section 1.3), determine the patches that
meet your specific needs.
If, after reading Sections 1.1 and 1.2 of these release
notes, you are unsure whether your hardware and software
meet the requirements for installing a particular patch, run
inst. The inst program does not allow you to install
patches that are incompatible with your hardware or
software.
Patch software is installed like any other Silicon Graphics
software product. Follow the instructions in your Software
Installation Administrator's Guide to bring up the miniroot
form of the software installation tools.
Follow these steps to select a patch for installation:
1. At the Inst> prompt, type
install patchSGxxxxxxx
where xxxxxxx is the patch number.
2. Initiate the installation sequence. Type
Inst> go
3. You may find that two patches have been marked as
incompatible. (The installation tools reject an
installation request if an incompatibility is
detected.) If this occurs, you must deselect one of
the patches.
Inst> keep patchSGxxxxxxx
where xxxxxxx is the patch number.
4. After completing the installation process, exit the
inst program by typing
Inst> quit
1.7 Patch Removal Instructions
To remove a patch, use the versions remove command as you
would for any other software subsystem. The removal process
reinstates the original version of software unless you have
specifically removed the patch history from your system.
versions remove patchSGxxxxxxx
where xxxxxxx is the patch number.
To keep a patch but increase your disk space, use the
versions removehist command to remove the patch history.
versions removehist patchSGxxxxxxx
where xxxxxxx is the patch number.
1.8 Known Problems INST SUBSYSTEM REQUIREMENTS No Requirements Information Available. INST SUBSYSTEM CHECKSUMS These checksums help to provide a 'signature' for the patch inst image which can be used to authenticate other inst images. You can obtain this kind of output by running sum -r on the image (from the command line): 05325 2 patchSG0003318 04310 533 patchSG0003318.eoe_sw 34672 3 patchSG0003318.idb INST SUBSYSTEM FILE LISTINGS The following lists the files which get installed from each subsystem in the patch:
