RHBA-2009:1151: bug fix update

• on 32-bit systems, core dumps for some multithreaded applications did not include all thread
information. (
BZ#505322
783
)
• a stack buffer used by get_event_name() was not large enough for the nul terminator sprintf() writes.
This could lead to an invalid pointer or kernel panic. (
BZ#506906
784
)
• when using the aic94xx driver, a system with SATA drives may not boot due to a bug in libsas.
(
BZ#506029

)
• incorrect stylus button handling when moving it away then returning it to the tablet for Wacom Cintiq
21UX and Intuos tablets. (
BZ#508275
786
)
• CPU "soft lockup" messages and possibly a system hang on systems with certain Broadcom
network devices and running the Linux kernel from the kernel-xen package. (
BZ#503689
787
)
• on 64-bit PowerPC, getitimer() failed for programs using the ITIMER_REAL timer and that were also
compiled for 64-bit systems (this caused such programs to abort). (
BZ#510018
788
)
• write operations could be blocked even when using O_NONBLOCK. (
BZ#510239
789
)
• enabling MSI on systems with VIA VT3364 chipsets caused a kernel panic or system hang during
installation of Red Hat Enterprise Linux or subsequent booting of the operating system. MSI was
enabled by default during boot and the "pci=nomsi" boot option to disable MSI was required on
Red Hat Enterprise Linux 5.2 and later to avoid this bug. With this update, the kernel automatically
disables MSI on VIA VT3364 chipsets during boot. The "pci=nomsi" boot option is no longer
required to install or boot Red Hat Enterprise Linux successfully. (
BZ#507529
790
)
• shutting down, destroying, or migrating Xen guests with large amounts of memory could cause other
guests to be temporarily unresponsive. (
BZ#512311
791
)
Users should upgrade to these updated packages, which contain backported patches to correct these
issues. The system must be rebooted for this update to take effect.

Updated kernel packages that fix an issue with HugeTLBfs are now available for Red Hat Enterprise
Linux 5.
The kernel packages contain the Linux kernel, the core of any Linux operating system.
These updated kernel packages fix the following bug:
• HugeTLBFS (Translation Look-Aside Buffer File System) allows much larger page sizes than
standard 4-kilobyte pages. The kernel's virtual memory subsystem uses these pages to map
between real and virtual memory address spaces, and HugeTLBFS allows for significant
performance increases for memory-intensive applications under heavy load. When a file existing
on the HugeTLB file system was accessed simultaneously by two separate processes, the system
become unresponsive and eventually a soft lockup occurred. These updated packages correct
