RHBA-2006:0457 - Bug Fix Advisory
Synopsis
crash bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated crash packages are now available.
Description
The crash package is used to investigate live systems and kernel core
dumps created from the netdump and diskdump packages.
The following issues were addressed:
If the starting point of a panicking task's backtrace was located
on the process stack, on a per-cpu IRQ stack, or on the per-cpu NMI
stack, the "bt" command found it as expected. But if the crash
occurred while operating on the other two exception stacks - the STACKFAULT
and DOUBLEFAULT stacks - the "bt" command showed an invalid backtrace
because those stacks were not searched. This version of the crash
utility searches all three 64-bit architecture exception stacks for the
panic task backtrace starting point.
The "vm -p" command option failed with a "pml page" read error when
run on a 64-bit architecture user process. This version of the crash
utility properly dumps the location of each page of user virtual address space.
Users of crash are advised to upgrade to these updated packages, which
resolve these issues.
