Hello All,  Just after a reboot I can insert a blank cd-writable
        disk & have no problems writing the cd .  But after the system has
        been running a while (with openwin & ...) if I insert a blank cd
        the cd-drive loops trying to read it or some such & then after ~
        6-8 tries begins to blink the access light red . 
        The dmesg output show -nothing- untoward concerning the cdrom or
        the the scsi subsystem .  below is the output from an attempt to
        write using 'cdrecord -v dev=1,6,0 -speed=1 "filename"' plus the
        dmesg from a clean reboot .

        Is there someway around this (without rebooting) ? 
        I remember seeing something concerning a problem with trying to
        write a cd under Virtual Consoles when switching to another VC
        but I beleive that the person said that he had no problems when
        burning in a xterm .  Any help gladly accepted & if further info
        is need just ask .  Tia,  JimL
