I have the same problem, it only started with Herd 5. One odd thing I noticed in my log is this:
[114364.279248] ide: failed opcode was: unknown [114364.279252] hdc: drive not ready for command [114364.279290] hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest } This is repeated over and over, slowing down my boot time. However, the drive functions normally, aside from the ghost CD. -- cd-rom ioctl claim a valid CD even if the drive is empty https://launchpad.net/bugs/46288 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
