Hasn't anybody had this problem? Compiling the ide-cd as a module
doesn't help. When I try to mount the cd after redocking, mount just
stops responding. Can't even shut it down. ps-aux shows /sbin/modprobe
-q -- ide_cd is running. Syslog shows now entries for hdc. I'd really
like to solve this problem - I don't feel like rebooting everytime I
need the cd. Awaiting your suggestions.

Thanks in advance,
