As a naive workaround, the following simple patch would prevent division
by zero and SIGFPE:
int round_div(int num, int den)
{
-return (num + (den / 2)) / den;
+return den ? (num + (den / 2)) / den : 0;
}
Reported values now would be zeros, which is certainly wrong, but at
least the pr
It happens because of division by zero in round_div() function, here's a
backtrace from gdb:
Program received signal SIGFPE, Arithmetic exception.
0x08048cc4 in round_div (num=0, den=0) at rovclock.c:180

Hi,
I also have a Radeon card and I don't get "floating-point exception".
Please note that I run Lucid with the default kernel and a more recent
