I have problems with cd's since upgrading from 3.4 to 4.0. I have two CD drives, one a CD-RW drive. The output from dmesg is: acd0: CD-RW <Hewlett-Packard CD-Writer Plus 7500> at ata0-slave using PIO4 acd1: CDROM <CREATIVE CD1220E> at ata1-slave using PIO4 Problem 1: (This was mentioned recently in -current concerning an HP8100) Trying to write a CD on the HP 7500 leads to the following: burncd -f /dev/acd0c data backup0408.ISO fixate next writeable LBA 0 writing from file backup0408.ISO size 537592 KB written this track 537592 KB (100%) total 537592 KB fixating CD, please wait.. burncd: ioctl(CDRIOCCLOSEDISK): Input/output error The message log has the following after this: Apr 8 09:17:12 c292731-a /kernel: acd0: CLOSE_TRACK/SESSION - ILLEGAL REQUEST asc=64 ascq=00 error=04 Apr 8 09:17:12 c292731-a /kernel: acd0: PREVENT_ALLOW - ILLEGAL REQUEST asc=64 ascq=00 error=04 Problem 2: If I am foolish enough to have a disk in either of the drives when I boot, it is impossible to mount them. For acd0c I get "device busy" unless I do a umount -f /dev/acd0c, but at that point trying to mount gives me mount_cd9660 /dev/acd0c /cdrom mount:cd9660: .: Not a directory (Prior to the umount, df shows the disk is mounted, but ls /cdrom shows nothing.) If I ensure the drives are empty on boot, I can at least mount and read disks. I have tried this with several different disks. My drives both worked fine under 3.4 (grumble, grumble...) Help or advice would be appreciated. (I know, I know, I can always wipe my system and do a clean reinstall of 3.4, but that seems like a solution dreamt up by the boys in Redmond.) Thanks in advance.
