PRODUCT: HP Tru64 UNIX [R] V5.1B-2 SOURCE: Hewlett-Packard Company ECO INFORMATION: ECO Name: T64KIT0025264-V51BB25-E-20050331 ECO Kit Approximate Size: 3.49MB Kit Applies To: HP Tru64 UNIX V5.1B-2/PK4 ECO Kit CHECKSUMS: /usr/bin/sum results: 07666 3570 /usr/bin/cksum results: 3241497080 3655680 MD5 results: 3e640fdf013484c303884479af466681 SHA1 results: afabf706113dd968521a519c05de060c8ee2b841 ECO KIT SUMMARY: A dupatch-based, Early Release Patch kit exists for HP Tru64 UNIX V5.1B-2 that contains solutions to the following problem(s): Under certain conditions, usage of GH memory (gh_chunks or rad_GH_regions) with new_wire_method enabled (= 1) can lead to a "vl_unwire: page is not wired" or kernel memory fault" panic. The typical failure of this nature yields stack traces like the ones shown below: "vl_unwire: page is not wired" panic vl_unwire u_map_wire lw_unwire_new vm_map_pageable rdg_unwire_iodesc rdg_post_snd rdg_io_post rdg_syscall syscall _Xsyscall "kernel memory fault" panic trap _XentMM vl_unwire u_map_wire lw_unwire_new vm_map_pageable rdg_unwire_iodesc rdg_post_snd rdg_io_post rdg_syscall syscall _Xsyscall Target Audience: Any customer running HP Tru64 UNIX V5.1B-1/PK3, V5.1B-2/PK4, or V5.1A PK6 with new_wire_method enabled while using GH memory. Customers that have already installed CSP kits T64KIT0024959-V51BB25-20050222.tar or T64KIT00248190V51AB24-20050203.tar do not need to install the ERP kit. The Patch Kit Installation Instructions and the Patch Summary and Release Notes documents provide patch kit installation and removal instructions and a summary of each patch.

INSTALLATION NOTES: 1) Install this kit with the dupatch utility that is included in the patch kit. You may need to baseline your system if you have manually changed system files on your system. The dupatch utility provides the baselining capability. 2) The patch in this ERP kit does not have any file intersections with any other ERP available at this time for this product version. 3) This ERP kit will NOT install over any Customer Specific Patches (CSPs) which have file intersections with this ERP kit. Contact your normal Service Provider for assistance if the installation of this ERP kit is blocked by any of your installed CSPs. INSTALLATION PREREQUISITES: You must have installed HP Tru64 UNIX V5.1B-2 PK4 (BL25) prior to installing this Early Release Patch Kit.
