When accessing the cdrom, the system hangs completely.

SAK still works and allows me to reboot, but sync and umount do not
appear to work during this hang. No other user programs appear
to be functioning, however network activity (this machine is a
firewall/router) passes through and is NAT translated correctly.

It looks as if this driver is no longer actively maintained by
John Weidman as there is no contact information for him in the
header, or in the MAINTAINERS file.

Kernel is 2.4.7, i686-300 128Mb ram

***********
The cdrom would eject itself, but the driver never returned control
to the 'eject' application, and hung in the above state.
At this point, i shut down, double-checked termination, and forced
it by adding a hard active terminator on the scsi bus after the
cdrom (only device on the bus) instead of relying on the CDROM's
built-in terminators

***********
at this point the system is again unresponse, and requires hard-reset
as before, the cdrom has ejected from the drive, but there has been
no return from the actual command.
