Hello there, I am getting a fatal due to usleep_thread syscall while simulating a few multithreaded configuration for inorder in ALPHA_SE. And this message seems to be preceded by a sequence of warnings like this: warn: context 0: XXX consecutive store conditional failures
It would be helpful to debug if I can have some comments on it. Are the warning and the panic really related? Also, when might a usleep_thread syscall get called? Couldn't find much info on google. The workloads comprise of spec 2k benchmarks and when run as a single thread finish without any problems. Here are the contents of the simerr file for the one of the workloads: warn: Sockets disabled, not accepting gdb connections For more information see: http://www.m5sim.org/warn/d946bea6 warn: ignoring syscall sigprocmask(1073070158, 1, ...)
