Hi,
I've bumped into pretty annoying feature of one NEC CD-ROM DRIVE:461, 2.3d.
It's normally like 6-speed CDROM, but if it encounters error, it slows
to 1x speed and after a while it changes back to 6x speed. If the
CD-ROM in drive is not quite as the NEC likes it, this means
periodic pauses in CD-ROM reading, as the drive tries to adjust speed.
This is very annoying especially when playing MP3 ;-)

Is it possible to somehow say the drive that is should stay
on some speed ? e.g. the driver in kernel would keep track of
how many read errors occured and force the drive to stay
on low speed if needed.
