Are you sure you got the right bisect? Manfred has a few ipc/sem.c patches in linux-next, starting at commit c50df1b4 (ipc/sem.c: cacheline align the semaphore structures), does reverting any of those instead of "ipc,msg: shorten critical region in msgrcv" help at all? Also, anything reported in dmesg? > The issue is present since next-20130606! > > LAST KNOWN GOOD: next-20130605 > FIRST KNOWN BAD: next-20130606 > > KNOWN GOOD: next-20130604 > KNOWN BAD: next-20130607 || next-20130619 || next-20130620 || next-20130621 > > git-bisect says CULPRIT commit is... > > "ipc,msg: shorten critical region in msgrcv" This I get. I went through the code again and it looks correct and functionally equivalent to the old msgrcv. > > NOTE: msg_lock_(check_) routines have to be restored (one more revert needed)! This I don't get. Restoring msg_lock_[check] is already equivalent to reverting "ipc,msg: shorten critical region in msgrcv" and several other of the msq patches. What other patch needs reverted? Anyway, I'll see if I can reproduce the issue, maybe I'm missing something.
