Problems with eject and pktcdvd

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Recently I bought a NEC ND-4551A CD/DVD writer. 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.

Part of my dmesg related to IDE:
