What udev rule? It's the kernel which need to know that this device isn't a tape but an optical drive. :)

ide-tape driving DVD burner is a "CANNOT happen" case...

Thomas, which kernel version is it? Please post a full dmesg output.

Seems that can happen Bart ;-)

it's a 2.6.26.5 kernel running on debian/testing.

I moved ide now to module

Could you also try 2.6.27-rc9?

I'm not able to run hdparam on /dev/hda, udev won't create the device file and if I create the device file manually hdparam just stop working.

I'd attached cat /proc/ide/hda/identify (hda.identify.txt.gz).

no changes in that kernel version .. I attachted output of dmesg of that kernel version.

what can I do ?
Bart, any idea what's going wrong here, or how to work around it?
ide-tape driving DVD burner is a "CANNOT happen" case...
Thomas, which kernel version is it? Please post a full dmesg output.
Seems that can happen Bart ;-)
it's a 2.6.26.5 kernel running on debian/testing.
I moved ide now to module
 alim15x3                7504  0 [permanent]

so this is a probing time device type misdectection (yeah, the impossible has just happened ;).
Does BIOS also detect this device as "HL)DP-ST@V@-RAI"?
yes
Quoted 4 lines
Please send the output of "hdparm --Istdout /dev/hda" so we can check whether the problem is a bogus (corrupted?) identify data or some issue with the device type detection code...
I'm not able to run hdparam on /dev/hda, udev won't create the device file and if I create the device file manually hdparam just stop working.

I'd attached cat /proc/ide/hda/identify (hda.identify.txt.gz).
Quoted 2 lines
Could you also try 2.6.27-rc9?
no changes in that kernel version .. I attachted output of dmesg of that kernel version.

Thanks. Does the following patch help?

That looks more like a hardware problem with a flakey bit. For example GH22LP20 with bit 2 always cleared = CH22HP20. DVD-ROM with bit 2 sometimes cleared = @V@-RAI. And the peripheral device type also has bit 2 cleared.

This would explain it nicely (I suspected something along these lines but failed to see the actual pattern). After all it is very unlikely to have _that_ broken firmware.

Thanks,
