10. Known problems as of 0.9pl13

Trying to 'talk' to other users with the talk binary from usr.tar.gz doesn't work for me. I always get this message:
```
[Couldn't bind to control socket : Cannot assign requested address (99)]
```
At ftp.informatik.uni-oldenburg.de you'll find a talk binary that works better. However, to talk to a user on the local machine, you have to write talk user@localhost instead of just talk user. I don't know if this is a problem of talk or the networking code - or probably it's just my system that's badly configured.
Trying to use a CD-ROM to play Audio CDs (this can be done with ioctl()'s) seems to be very unstable, too. Probably with more and more users with CD-ROM drives discovering this effect, bugs will soon be found and squashed. Right now simple commands like CDROMPLAYTRKIND seem to work, but more complex commands like CDROMREADTOCHDR fail with SCSI timeout messages. The low-level part of the SCSI driver (drivers/scsi/wd33c93.c) requires some rework to do its job better. Volunteers?
