20.5. Bug Fixes

kdump no longer hangs due to the attempts to read the memory from on-board devices

On the little-endian variants of IBM Power Systems hardware, the kdump mechanism became unresponsive because the kernel attempted to read the memory from on-board devices such as the GPU, and include it as a part of the vmcore. This update fixes kexec-tools to skip the on-board devices when attempting to read the memory during kdump. As a result, kdump now works correctly, the vmcore is saved to disk and the operating system reboots as expected. (BZ#1478049)
