Enhancements

BZ#902141

Currently, dump files created by the makedumpfile utility using the snappy compression format are now readable by the crash utility. The snappy format is suitable for the crash dump mechanism that requires stable performance in any situation with enterprise application use.

BZ#902144

With this update, dump files created by the makedumpfile utility using the LZO compression format are now readable by the crash utility. The LZO compression format is fast and stable for randomized data.

BZ#1006622

This update adds support for compressed dump files created by the makedumpfile utility that were generated on systems with physical memory requiring more than 44 bits.

BZ#1017930

This update fixes faulty panic-task backtraces generated by the bt command in KVM guest dump files. The bt command now shows a trace when the guest operating system is panicking.

BZ#1019483

This update fixes the CPU number display on systems with 255 or more CPUs during the initialization, by the set command, the ps command, and by all commands that display the per-task header consisting of the task address, PID, CPU and command name. Without the patch, for CPU 255, the sys command displays "NO_PROC_ID", and the other commands show a "-" for the CPU number; for CPU numbers greater than 255, garbage values would be displayed in the CPU number field.
