ieee1394: Node 01:1023 has non-standard ROM format (0 quads), cannot parse

Hello.

I just got a new plextor combo (read dvd, write cd) drive and installed it into my firewire drive enclosure. The CD-ROM drive that was in there previously was working fine. I am using an Audigy as my firewire controller.

Now, on attach/power on/modprobe ohci1394/etc I get this message:

ieee1394: Node 01:1023 has non-standard ROM format (0 quads), cannot parse

I get the same message with 2.4.20, .21-pre3, and 2.5.59.

I've tried increasing the number of attempts that the loop in nodemgr.c makes to attempt to get this quantity from 4 tries (1 second) to 40 (10 seconds.) The only difference that made was that the error takes longer to appear.

Not sure if this is useful information, but this is what it says with the CD-ROM drive in (ie: when it is working)
ieee1394: Device added: Node[01:1023] GUID[0030999550551539] [NewMotion Technology Corp. ]

I've googled and searched the list archives at no avail. IRC also isn't working out.

If anybody has experienced this before, has any ideas, would like information about the problem or even knows of a better forum to direct this question to, your help would be greatly appreciated. Please CC: me a copy of your reply as I am not on the list.

Thanks in advance,
Ryan

Every 1394 device is required to have a Config ROM directory. The directory has to be _atleast_ 4 quads for basic information to be extracted and allow the subsystem to use the device. Without even 1 quad it cannot even verify the magic '1', '3', '9', '4' quad at the start of it.

If one cdrom works in the enclosure and another doesn't, then I suspect something is weird with the enclosure's detection of the device you placed in it. Are you sure that the master/slave jumpers are set correctly for the enclosure? Anything else it needs?

http://www.linux1394.org/ has a compatibility list. You can also email [email protected].

They were both set to master. The enclosure itself doesn't have any jumpers really, but I changed the jumpers around on the dvd drive (after receiving your email) and tested various combinations (ie: master, slave, cable select, and the DMA jumper on/off.) None of these worked.

Some other stuff I played with: I noticed that the drive locks shut with the 'busy' light on. but:
- drive not connected to enclosure: eject works, busy light off
- drive connected to enclosure, but enclosure not plugged into firewire bus (ie: controller card): eject doesn't work, busy light on
- connected, on the bus, ohci1394 module not loaded: eject works, busy light off
- connected, on bus, ohci1394 loaded: eject doesn't work, busy light on

Also, transitioning from one of the 'working' states to one of the non-working states doesn't work (ie: the unloading the ohci1394 driver.) The drive gets "stuck" in it's busy-not-working state until you powercycle the enclosure.

Is it possible that my enclosure just doesn't support DVD drives?

Thanks again

Is the enclosure specific to CD drives? I always thought they were generic IDE enclosures. If it is specific to CD, then there's a good chance it doesn't like it. Check with the enclosure manufacturer.

I bought it as a generic enclosure (claiming to take cdrw/harddrive, no mention of DVD). I put my CDROM in it and it JustWorked(tm). Same with harddrives. The plexcombo is the first thing I've put in it that doesn't work. I think I am going to do some more testing (I have a friend with an iBook...) to find out where the problem lies.

Thanks for your help.

I also see that error with 2.5.59 and an external maxtor drive that works fine with 2.5.58 and revision 744 of the ieee1394 svn tree.
