aic7xxx: first mount always fails

aic7xxx: first mount always fails

[David Santinoli]

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).

My guess is that your CDROM drive takes longer than most to perform
the initial read capacity.  There is little to be done for this other
than uping the timeout value in the CD driver.

It was a hardware issue indeed - an upgrade of the drive firmware solved the
problem.
