This time it is a "kernel BUG at fs/nfsd/nfs4state.c:1044" Since the machine was not responsive after the BUG and rebooted I was only able to take a picture of the full stacktrace. You can download it from here: https://ferdi.naasa.net/url/jplatte/IMG_3139.JPG The patch "[PATCH] rpc_pipefs: allow rpc_purge_list to take a NULL waitq pointer" was not applied for this trace, but the bug is the same with this patch applied. So there must be another problem. The crash is reproducable just by creating some nfs traffic and I can hit it within minutes. regards, Joerg -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
