It works OK with one exception. When I have a packet device associated with the drive, there are problems with ejecting discs. Here is an example: 1. Insert a CD-R/DVD/CD-RW (whatever) 2. mount /media/cdrom0 3. umount /media/cdrom0 Now the eject button doesn't work, when I issue the eject command I get: hda: irq timeout: status=0xd0 { Busy } ide: failed opcode was: unknown hda: DMA disabled hda: ATAPI reset complete After few seconds eject ends with no result. Second eject command works. There are no problems without the packet device association (turned off/on with pktsetup using /etc/init.d/udftools). My system if Ubuntu 5.10 The kernel is: Linux amd 2.6.15-mm3 #1 PREEMPT Sun Jan 15 12:31:14 CET 2006 i686 GNU/Linux But it works the same way with 2.6.15.
