Doc Type: Bug Fix
Doc Text:
* The bt command displays a task's kernel-stack backtrace. When running this command against an x86 Xen kernel vmcore, crash did not correctly handle the transition from the IRQ stack back to the process stack, leading to a segmentation fault. The version of crash provided with this advisory contains a patch that corrects this issue, allowing users to analyse a vmcore file from a system with an x86 Xen kernel.
