I've made the patch on top of > 3.10.0-rc7-next-20130625 LTP msgctl08 hangs on 3.11-rc7 (ARC port) with some of my local changes. I bisected it, sigh... didn't look at this thread earlier :-( and landed into this. ------------->8------------------------------------ 3dd1f784ed6603d7ab1043e51e6371235edf2313 is the first bad commit commit 3dd1f784ed6603d7ab1043e51e6371235edf2313 Author: Davidlohr Bueso <davidlohr.bueso@xxxxxx> Date: Mon Jul 8 16:01:17 2013 -0700 ipc,msg: shorten critical region in msgsnd do_msgsnd() is another function that does too many things with the ipc object lock acquired. Take it only when needed when actually updating msq. ------------->8------------------------------------ If I revert 3dd1f784ed66 and 9ad66ae "ipc: remove unused functions" - the test passes. I can confirm that linux-next also has the issue (didn't try the revert there though). 1. arc 3.11-rc7 config attached (UP + PREEMPT) 2. dmesg prints "msgmni has been set to 479" 3. LTP output (this is slightly dated source, so prints might vary) ------------->8------------------------------------ <<<test_start>>> tag=msgctl08 stime=1377689180 cmdline="msgctl08" contacts="" analysis=exit initiation_status="ok" <<<test_output>>> ------------->8-------- hung here ------------------ Let me know if you need more data/test help. -Vineet
