Summary: [ltp] ltp test cases will crash occasionally in SMP kernel

Details:

LTP cases will crash from time to time in SMP kernel. But I can't reproduce these crashes manually.

Cases that ever crashed are rename09, mkdir02 and mkdir04.

Follow-ups

--- Graf Yang 2008-07-08 23:53:24

Please check /etc/passwd, there should be one account named bin, or else

rename09, mkdir02, mkdir04 will crash.

--- Graf Yang 2008-07-15 03:13:44

It's not the ltp test application bug, please check the file /etc/passwd.

--- Vivi Li 2008-07-28 06:47:31

I modified the ltp test script to make sure passwd is copied to /etc.

OK now. Close it.
