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 processors1.2 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.unix1.6 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> quit1.7 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:
