and it is working fine since I have installed it 2 years ago.
I have just had the first problem with it.
My kernel is 2.0.23 with isofs module loaded.
The IDE "controllers" installed on my computer are two cheap-o-matic
(10$) IDE interfaces configured one as primary and the other as secondary
IDE. The primary have 2 IDE disks attached to it and the secondary have
one IDE disk as master and the CDROM as slave.
I have mounted the CDROM 10 minutes ago and after some inactivity I have
accessed it. Just a 'cd' into a directory of the CD, using the pathname
completion of the zsh.
The zsh freezed hard with the secondary IDE controller led light.
The dmesg reports:

After the last message the CDROM relaxed and started to work again (I'm
accessing the CDROM just right now without the need for a reboot!).
Note that my main Linux hard disk (1 gig segate) is attached as master to
the secondary controller, so I'm sure the controller is working okay.
What's going on ?
Ciao,
Riccardo.
