Hello, I had since the latest 2.6 kernels lockups in a sheevaplug computer (without swap), when it reached OOMK conditions. The machine was in such a deadlock that it only answered to sysrq request through the serial console. Almost every OOMK caused this, so once you reproduce an OOMK, I think it will almost sure hang the system. The lock looks related to swapping in read-only pages of programs. As I recently experienced reiserfs lockups in a desktop pc (http://www.spinics.net/lists/reiserfs-devel/msg03157.html), I wondered if those OOMK lockups could happen due to the reiserfs of /. So I moved / to ext4, and all locks disappeared. OOMK works fine now. So I'm definitely leaving reiserfs due to the deadlocks; a pity, because it served very well to me for many years. I'd be glad to use it again with fixed deadlock troubles. If it's of help of anyone, here is the log (since just before the OOMK) taken by netconsole, linux 3.4.1, and with some sysrq dumps. Since the OOMK message appears, the machine answers to nothing but sysrq requests. The log: http://viric.name/tmp/hang/sheevaplug-hang1.txt.gz Regards, Lluís. -- To unsubscribe from this list: send the line "unsubscribe reiserfs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
