cdrom: This disc doesn't have any tracks I recognize!

This happens while calling command pktsetup.

Well that's very strange.

long do_sys_open(int dfd, const char __user *filename, int flags, int mode)
{
        char *tmp = getname(filename);
        int fd = PTR_ERR(tmp);

        if (!IS_ERR(tmp)) {
                fd = get_unused_fd();
                if (fd >= 0) {
============>           struct file *f = do_filp_open(dfd, tmp, flags, mode);
                        if (IS_ERR(f)) {
                                put_unused_fd(fd);
                                fd = PTR_ERR(f);
                        } else {
                                fsnotify_open(f->f_path.dentry);
                                fd_install(fd, f);
                        }
                }
                putname(tmp);
        }

do_filp_open has returned 0x8000002

Isn't that a SCSI error of some kind?

IAC we have tried to do fsnotify_open(f->f_path.dentry) with that result...

I can confirm the same oops on 2.6.20-ck1 with pktcdvd either as
module or as built-in.

I can assume perhaps this is not so much an issue with the pktcdvd
driver as it is with the libata drivers and scsi.  Beats me, I'll
leave it up to you.
