HP Tru64 UNIX and TruCluster Server Version 5.1.B-4 Patch Summary and Release Notes (13156)

• Fixes a problem in the alt driver for DEGPA Gigabit Ethernet adapters. This problem affects
all Tru64 UNIX systems containing DEGPA network interfaces.
• Fixes a condition that causes a system hang when using open3D over the AGP bus on an
AlphaServer GS1280.
• Fixes a problem that can cause an ES45 to hang if the Xserver is restarted or the system is
rebooted without a power cycle when using the Radeon AGP graphics device.
• Fixes a problem with USB hubs (or any other bus device) that occurs when they are removed
from a running system.
• Fixes a performance problem that occurs when doing wiring on gh_chunks memory.
• Fixes multiple problems affecting a system with peripheral USB hubs attached, as well as
problems that might occur when moving or adding USB host adapters.
• Fixes a situation in which mounting a valid CD-ROM for the first time fails with the message
“No valid file system exists on this partition,” although subsequent mounts of the same
CD-ROM work as expected.
• Fixes a kernel memory fault for systems that contain more that 8 IDE/ATA buses.
• Corrects rounding errors for vm attribute vm_bigpg_thresh.
• Corrects the handling of bad pages when big pages are enabled.
• Fixes the cause of "page mapped" panics when using mmap calls with dev/mem to access
free big pages.
• Corrects a problem in which Incorrect I/O status may be returned by the KZPEA driver
when attempting to abort an I/O during a reset.
• Adds support in the platform code to handle MSI capable adapters. AlphaServer GS1280
systems support option cards that require MSI capabilities.
• Installs the V1.07 release of the ciss driver, which is the minimum version required to support
the Smart Array 5300 controller.
• Corrects a problem in which a path event can cause hang in cdisk_online during disk open
of HSG80.
• Provides additional environmental support for the DS20L platform.
• Allows multiple VX1 graphic cards to be configured in a separate I/O box system.
• Adds support to get live status information for air movers and power supplies on AlphaServer
GS1280 systems and to log intrusion packets to the error log.
• Adds support for CPU indictment on AlphaServer GS1280 systems.
• Corrects problems with the time of year (TOY) clock.
• Fixes an IDE/ATA bus hang caused by attempting to complete raw odd byte DMA transfers
to or from IDE/ATAPI devices.
• Addresses small memory leaks within the kernel that occur infrequently.
• Adds sysconfig tunable attributes for AlphaServer ES45 environmental monitoring.
• Addresses an issue in which a NULL Inquiry data causes a “Device has no 'name' ” error
and possible I/O stalls.
• Corrects the cause of a delete_pv_entry panic when kernel virtual address space has high
usage.
• Fixes a problem in which Smart Array 5300 logical volumes are counted as RAID controllers.
• Address an issue in which AdvFS domain panics occur during HSZ and HSG failovers.
• Improves I/O performance by reducing kernel locking overhead.
• Fixes a small memory leak in Power Management code.
• Prevents unnecessary retries on an HSG80 when fail unit attention with ascq = Oxf002 and
returns proper error to higher layer.
• Fixes the IDE/ATAPI driver's reset logic to prevent a kernel memory fault when booting
and to properly detect and log all master and slave reset failures when the system is
operational.
