Resolved Date: Feb 22, 2018
Previous ID: LIN5-4422, LIN6-3030
Found In Version: 6.0
Severity: Severe
Applicable for: Wind River Linux 6
Component/s: BSP - Async
Host OS: Linux Red Hat
Architecture: MIPS
The CGL kernel would hung on some multi-thread programs in the LTP, POSIX and KTS.
1. There were some defects on the mips arch "CONFIG_PAX_MPROTECT" implement, so need disable it.
2. The "CONFIG_PAX_RANDMMAP" also impact some test cases execution, need patch the following patch on the mips arch.

The bcm-xlp BSP pthread create operation would print following information:
