So basically I can not install a signal handler to catch freeze signal in the process. Right? Is there any other way to solve the problem I am facing? After resume some of the system calls are failing in some of my applications with errno set as EINTR. I wanted to explore a way to not check for this error all over the place and somehow retry failed system call. Any ideas?

Sure.
It's in kernel/signal.c (get_signal_to_deliver) for x86 and x86_64, and arch/<name>/kernel/signal.c for other arches. The support for other arches is the place x86 & x86_64 used to use - I wonder if they should be going away (Rafael cc'd to raise this point with him).
