upstream commit
https://git.fedorahosted.org/cgit/lvm2.git/commit/?id=0baf66a992fbac92fa2c30e9bb8e74a5535ff45a

pulling latest git source code for lvm2 , compiling with debian
./configure options (taken from last lvm2 package log from
https://buildd.debian.org/status/fetch.php?pkg=lvm2=sparc64=2.02.141-2=1454711070
) and running , does not return bus error.

PS: thanks for fix to Zdenek Kabelac

You don't have to mention the previous bug report here, your
message is automatically appended to the existing bug report
the moment you CC the bug report's address :).

Interesting. Can you post the version numbers for lvm2 taken from
the Debian package? I have had a look at the lvm2 git repository
and there don't seem be any big changes after 2.02.142 which
could cause this issue. If we can pinpoint the change that fixed
the bug, we could just cherry-pick the necessary patch.

Adrian

Bug#809685: lvm2 on sparc64 = bus error

2016-01-02 Thread Anatoly Pugachev 
Package: lvm2
Version: 2.02.138-1
Severity: important

Dear Maintainer,


   * What led up to the situation?

installed sid/unstable to sparc64 LDOM, any commands from lvm2 give "bus error":

root@deb2g:~# lvm vgs
Bus error
root@deb2g:~# lvm pvs
Bus error
root@deb2g:~# lvm lvs
Bus error

   * What exactly did you do (or not do) that was effective (or
 ineffective)?


I have to recompile lvm2 debian package with debug info, to provide a
more useful bug report:

$ export DEB_BUILD_OPTIONS="debug nostrip noopt"
$ fakeroot apt-get source -b lvm2
$ dpkg -i *.deb

set ulimit -c to unlimited and generated core dump:

root@deb2g:~# lvm lvs
Bus error (core dumped)
