Package: mdadm Version: 3.4-4 Tags: patch Control: -1 forwarded http://marc.info/?l=linux-raid&m=147515212602202 X-Debbugs-Cc: debian-sparc@lists.debian.org User: debian-sparc@lists.debian.org Usertags: sparc64 Hi, When mdadm tries to examine MBR partition records (such as when creating an array using already-formatted disks), it does so with an unaligned pointer, which leads to a bus error (SIGBUS) on sparc64. Please see the patch I have submitted upstream, which makes sure the accesses always go through boot_sect, since it is of type `struct MBR', which is the packed containing struct, and so the compiler will generate the correct code to perform the unaligned accesses when needed.

Hi, Upstream adopted your patch with commit 8e2bca51 in October 2016.

Closing. Kind regards, Felix Lechner
