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

• Fixes a problem in the PCI bus code that can prevent some functions on a
multifunction PCI card from being configured.
• Fixes a problem with the USB keyboard driver that affects keyboard operation
when the X server is not running. Specifically, the autorepeat function it may
appear jumpy, or keys may appear to press themselves after they are released.
• Fixes a problem relating to gh_chunks allocation on some configurations.
• Fixes various problems in the bcm driver for DEGXA Gigabit Ethernet adapters.
• Provides the logging of an informational event to the errorlog when the peripheral
driver is unable to get a user specified IDENTIFIER for a storage array device.
• Fixes CAM errors that occur when opening CD devices containing blank media.
• Corrects a problem in which a read or write operation to a changer device creates
an unkillable process.
• Fixes a problem that can cause a kernel memory fault during boot if a Fibre Channel
LSM boot disk is not discovered during the device probe.
• Suppresses an in_cksum() console debug message.
• Fixes a memory fault condition in the user agent driver that occurs when multiple
threads issue I/Os on different CPUs.
• Fixes jitter problems in 24-bit depth on VX1 graphics cards with certain date codes.
• Fixes the cause of a system crash that can occur if the hwmgr command deletes a
disk while it is in recovery.
• Increases BOOTP error timeout values for RIS kernel installations.
• Updates the values in the header of the PCI subpackets.
• Corrects problems that can result in changer devices not responding or in a kernel
memory fault when the FNDELAY flag is set in changer open and changer ioctl.
• Allows multiple PCI-X devices on a system to use Message Signaled Interrupts
(MSI).
• Reduces the existing limitation on the number of CPUs that can be taken off line
by allowing the other CPUs in the system to handle the interrupts coming from
up to two IO7s.
• Corrects a "simple_lock: time limit exceeded" issue that can occur in the CAM I/O
subsystem when MCS locking is disabled.
• Fixes a problem that turns off the reporting of correctable errors forever on any
CPU, except CPU 0, once the throttling of correctable errors has begun.
• Causes the posting of environmental events in the event of a machine check on
EV7-based platforms.
• Corrects a problem on AlphaServer ES45 platforms that resets sysconfigtab settings
for the attribute titan_sys_ps_hotswap after a system reboot.
• Provides modifications for possible future emx hardware.
