One of the obvious problems here is that the system is out of swap space and all of the memory is anonymous, OOM killing is exactly what the system should do. As far as thje panic is concerend, that is a bug somewhere. I dont have an s390x system and I dont know how to interpret the traceback. Perhaps Pete could tell me where __put_unused_buffer_head died? Larry reproducable with .5GB swapfile enabled using u4-beta kernel; As Tom stated, the OOM stuff is not what we want to chase, the panic is a problem though. I believe I can reproduce on s390 as well; though I need to double check before I commit to it. *** This bug has been marked as a duplicate of 123353 *** Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
