The first attempt at mounting a disc in my Traxdata CDR drive after boot always
fails. From the second on, everything works flawlessly.
Current setup is 2.2.18 kernel + 6.1.11-2.2.18 patch, but I've been experiencing
this behaviour since I bought the adapter (around 2.2.12 or so).
aic7xxx gets loaded as a module.
Here's some diagnostic info from the failed mount. If more is needed, please let
me know.
(of course, a disc _is_ present in the drive).
