Hello Linux-Arm folks,
We're seeing a really strange problem over here running on an EBSA-285 style
prototype (ARM110) card. It's an eLinux project featuring a 2.4.0-test9
kernel
with corresponding Russell King patch.
The problem is the serial port console suddenly dies when the newly ported
cron daemon is killed with -TERM option. I'm not sure yet if the whole
system is
brought down, but the console freezes every time the daemon is stopped (ie
killed).
I looked where crond was when the kill occurred and found out it's always
when the
cron daemon is in sleep( ) ! So I wrote a very simple program which showed
the
problem occurred in fact while the program was calling sleep:
int main(argc, argv)
int argc;
char *argv[];
{
while(1) {
sleep(30);
}
return 0;
}
I also found out that starting and killing crond (or the simple test, above)
by hand
worked ok, i.e., I could kill the processes without hanging. It's when a
runlevel script
(rc3.d) starts the daemons that I consistently see the hang problem.
Our toolchain is based on:
binutils2.10.1
gcc2.95.2
glibc 2.1.3
The packages as well as the (applied) ARM patch for gcc 2.95.2 came from
ftp.netwinder.org. Does anyone have any ideas what could be happening here?
Thanks, Louis
