HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

• Fixes a problem in the KZPCA itpsa driver that occurs when a SCSI target presents
multiple LUNs.
• Prevents problems in the USB subsystem, including memory leaks, data
inconsistencies, and USB device configuration problems.
• Installs Version 1.11 of the ciss driver.
• Fixes problems in the USB driver layer, inc.luding minor performance degradations
and device failures.
• Reduces the delay with hwmgr of EV7 based machines by reducing the number
of calls to the console to update sensor data.
• Fixes several IPMI-related problems, including the following:
— Erroneous fields in 686 OS-detected environmental machine check logout frame.
— Unusually large number of 686 sensor timeouts with heavy system load.
— IPMI always reporting -48v sensors as broken, seen as "redundant power supply
failed" messages
— An IPMI memory leak
• Restores the well known panic strings "Processor Machine Check" and "System
Uncorrectable Machine Check," which had been replaced by more specific error
strings. With this patch, both the old panic strings and the more specific ones will
be issued.
• Adds recognition for possible future devices.
• Adds the capability for KZPCA devices to work with SCSI devices that only support
asynchronous data transfers.
• Fixes a problem in which the SDLT media causes bus resets.
• Corrects problems that can result in tape devices not responding or in a kernel
memory fault when the FNDELAY flag is set in tape open and tape ioctl.
• Addresses an issue in which I/O may not complete under certain circumstances.
• Installs version 1.12 of the ciss driver to correct a condition that causes an
AlphaServer GS80 to hang following an Smart Array 5300 reset.
• Corrects lockmode 4 problem in cdisk_event_notify.
• Corrects a condition in which a system may panic with a kernel memory fault
when a device that is being opened by one program is being deleted via the hwmgr
utility.
• Corrects an illegal instruction that causes a rare system crash.
• Fixes a problem in which the user cannot connect to a printer on the parallel port
after cancelling a print job.
• Adds support for EV7 class machines (for example, the AlphaServer GS1280) to
allow the use of processors having different speeds in the same chassis.
• Corrects a condition in which the KZPEA firmware fails to correctly handle file
marks with odd byte transfers.
