Hi,
While attempting to make my el-cheapo ide cdrom work with FreeBSD, I
noticed the following problem with atapi.c. During atapi_probe(), an
atapi_wait() is called before sending an identify request to the device.
This causes a busy timeout if the cdrom is the only device on the controller.
Removing the following lines seemed to fix it for me ( using 2.1.5-RELEASE
sources ).
If other people are having problems with ATAPI cdroms, I suggest trying
this out.
Ivan...

< /* Wait for controller not busy. */
< if (atapi_wait (port, 0) < 0) {
< print (("atapiX.%d at 0x%x: controller busy, status=%b\n",
< unit, port, inb (port + AR_STATUS), ARS_BITS));
< return (0);
< }
