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

• 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.
• Corrects a potential system crash when shutting down after using a DAPBA or
DAPCA ATM adapter.
• Prevents an IDE bus hang caused when issuing a play audio track command from
scu to an ATAPI CD-ROM containing an enhanced CD.
• Installs Version 1.08 of the ciss driver.
• Fixes a problem with non-U.S. USB keyboards used in non-U.S. locales in which
the keyboards are treated as U.S. keyboards by the operating system.
• Fixes various problems in the bcm driver for DEGXA Gigabit Ethernet that can
cause crashes.
• Corrects a problem in the marvel_pfm driver where xmesh and bmesh incorrectly
reported 100 percent utilization for IO7 ports held in reset. Previously, this had to
be corrected by using the mvfi test program.
• Makes it possible for CPUs that do not take interrupts (either directly from the
attached IO7 or indirectly from IO7s attached to offlined CPU) to always be allowed
to be offlined.
• Verifies path structures in ctape_ioctl and ctape_generic_passthru to prevent a
kernel memory fault if the tape was opened with FNDELAY flag set.
• Prevents a recursive panic situation on the ES47 platform when a double bit
memory error is detected.
• Corrects a condition to prevents erroneous “ccfg_MakeDeviceIdentWWID: Invalid
device ID” messages from being generated.
• Fixes a problem that may cause a panic if the Xserver is stopped.
• Fixes a process hang in ubc_common_lookup.
• Corrects a problem in which the BBR code logs all error messages as soft error,
even if the error was not recovered and it failed to do the bad block replacement.
• Fixes a condition that causes a rare hang in the hardware configuration subsystem.
