 It is still crashing for me with a current kernel from June the 3rd.
 I tried to install acrobat which requires some packages and it allways crashed
 while installing suse_freetype2
 
 The lines with the unknown note type looks bad. Some strange non ascii chars.
 From /var/log/messages:
 
  /usr/pkg/emul/linux/sbin/ldconfig: bad tag 1: [4 4, 16 4,  GNU  PaX]

 And that was what I saw on the serial console:
