Source: linux-2.6 Severity: wishlist Tags: patch Now that we ship debug info, missing CONFIG_CRASH_DUMP=y is the only thing preventing users of stock Debian kernels from easily taking crash dumps with makedumpfile/kdump-tools and analyzing them with the crash utility.
I have built a kernel with the attached patch (against dists/sid/linux-2.6/debian) to verify that it builds and that it allows makedumpfile to successfuly take a crash dump. -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.38-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- John Wright <j...@debian.org>
