[Bug 767322] Re: unity_support_test crashed with SIGSEGV in nouveau_reloc_emit()

Wed Nov 9 02:51:47 UTC 2011

Hey koumus,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently.  So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that.  Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open.  I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

** Changed in: libdrm (Ubuntu)
       Status: Confirmed => Incomplete
