Hi,
I am getting fault on x86/Microblaze for ppoll. It is run only one
testcase than ends.
Have you ever met with this problem?
Thanks,
Michal
[monstr@monstr ppoll]$ ./ppoll01
ppoll01 0 TINFO : (case00) START
EXPECT: return value(ret)=(N >= 0) errno=0 (Success), r/w check=OK
RESULT: return value(ret)= 1 errno=0 (Success), r/w check=NG
ppoll01 0 TINFO : (case00) END => NG
ppoll01 0 TINFO : (case01) START
[monstr@monstr ppoll]$ echo $?
130
[monstr@monstr ppoll]$
