hy,

when I'm trying to re-scan the IDE devices, I get Input/output error,
meaning ide_register() function fails... why, and how to fix?

kernel: 2.2.10

void
rescan_hwif(int channel)
{
int fd;
int ide[][3] =
{
{0x1f0,0x3f6,14},{0x170,0x376,15}
};

fd=open("/dev/hda", O_RDONLY);
ioctl(fd, HDIO_SCAN_HWIF, ide[channel]);
perror("ioctl");
close(fd);
}

thanks,

mauzi
