Re: ata port is slow to respond

BTW, I've just downloaded and installed new 2.6.20-9 kernel, but it doesn't resolve this problem.

Re: ata port is slow to respond

Wow, I found the solution!!!!

The problem was the follows (from http://www.thinkwiki.org/wiki/Proble...not_recognized):

"The ata_piix SATA driver grabs ownership over the IDE ports when it is loaded, but (by default) does not support PATA ATAPI devices such as the Ultrabay optical drives. Thus, if the ide driver is compiled as a module and loaded after ata_piix, the DVD drive will not be recognized by either driver."

I've just did:

echo options libata atapi_enabled=1>/etc/modprobe.d/atapienable && update-initramfs -u

After reboot my cdrom and dvd drives were recognized correctly, I have them as /dev/hda and /dev/hdb.

Life is beautiful!!!

Re: Problem with CDROM and DVD writer

I have to say that I jumped to conclusion before time. Only once my drives was recognized correctly and never after. I even tried to compile new 2.6.21-rc1 kernel from kernel.org but situation happened again. Nobody has the same or similar problem?

Any suggestions? Help me, pls!!!

Re: Feisty can't find CDROM and DVD writer

I really don't understand what is going on with my box. Today I ran Herd 5 live cd and everything was cool - cd and dvd drives was recognized as hda and hdb. But (!) after installing on hard drive they are disappeared and annoying messages like "ata1: port is slow to respond, please be patient (Status 0xd8)" appeared again and again!!! I only discovered that cdrom drives on Herd 5 live cd activated by ide_cdrom module in kernel.

Guys, can anybody tell a couple of sophisticated words about that?

Re: Feisty can't find CDROM and DVD writer

Hmmm, it looks like the same bug as I have: https://launchpad.net/ubuntu/+source....15/+bug/53754
but with 2.6.15 kernel. And here is a thread on ubuntu-mailing list with the same problem: https://lists.ubuntu.com/archives/ke...ch/025438.html. Still no solution. The only way to solve is rmmod ati_piix and then depmod ati_piix. After that cd and dvd drives become recognized. But start k3b takes still a very long time due to hardware probing (starting hald device manager and then udevs).

Re: Feisty can't find CDROM and DVD writer

I discovered that I have also messages like: intel_rng: FWH not detected. I blacklisted intel_rng module and after reboot I've seen my cd and dvd drives after some time (what a ...?). What was a reason for that? It is unclear for me. But scary messages still appear:

[ 1052.762322] ata3: port is slow to respond, please be patient (Status 0xd8)
[ 1075.743913] ata3: port failed to respond (30 secs, Status 0xd8)
[ 1075.743927] ata3: soft resetting port
[ 1076.227231] ata3.01: failed to IDENTIFY (I/O error, err_mask=0x1)
[ 1076.227239] ata3.01: revalidation failed (errno=-5)
[ 1076.227249] ata3: failed to recover some devices, retrying in 5 secs
[ 1081.223750] ata3: soft resetting port
[ 1081.870978] ata3.00: configured for UDMA/33
[ 1082.034741] ata3.01: configured for PIO2
[ 1082.034787] ata3: EH complete

I think it is not a solution. Something else must be a reason for it.

Re: Feisty can't find CDROM and DVD writer

Note to ubuntu developers:

Please see the thread on linux-ide list: http://www.spinics.net/lists/linux-ide/msg08815.html or full massages: http://www.spinics.net/lists/linux-i...ads.html#08815

The resume is as follows:

My CDROM drive works just fine in PIO mode with pdc202xx_new
IDE driver (it doesn't support ATAPI DMA at the moment) and fails
with pata_pdc2027x libata (even with DMA blacklist patch from Albert).

So, to make it available on my box I had to disable ata_piix, configure the IDE pdc202xx_new driver and remove the libata pata_pdc2027x driver from kernel config, and recompile kernel.
After that I've got my drives as /dev/hda and /dev/hdh.

I think it is good idea to wait a little and do not enable new libata modules in the new kernels for feisty. I hope that ubuntu developers read this forum from time to time.

Re: Feisty can't find CDROM and DVD writer

I'm suffering the same problem, I believe. In Edgy, the same Asus ATA CD/DVD drive functioned perfectly, and it runs fine under Elive, so I know the hardware is fine. Here's what gnomebaker pukes up when I try to burn a CD:

wodim: No write mode specified.
wodim: Asuming -tao mode.
wodim: Future versions of wodim may have different drive dependent defaults.
scsidev: '0,1,0'
scsibus: 0 target: 1 lun: 0
TOC Type: 3 = CD-ROM XA mode 2
scsidev: 'ATA:0,1,0'
devname: 'ATA'
scsibus: 0 target: 1 lun: 0
wodim: No such file or directory.
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

In System Settings, the CD ROM drive is "enabled" and shows no signs of a problem. For some reason it is mounted at /proc -- is that where Ubuntu wants it? I'm surprised it is not at /media with the hard drives. Oh well, I don't think that matters.

I'll be alert for a fix to this. Good thing I have elive on the other drive!

Re: Feisty can't find CDROM and DVD writer

No, it definitely shouldn't be mounted under /proc. Try making a fstab entry for it or mounting it by going to media:/ in Konqueror.

Re: [partially solved] Feisty can't find CDROM and DVD writer

Well, after series of tests here is the final opinion from linux-ide people:

I second Albert's opinion. Please report this to ubuntu people so that
the origin of the problem can be fixed.

Thanks a lot. I admire your ability and patience in tracking these
difficult issues. :-)

My question to k/ubuntu developers : Can you figure out how to find solution of this problem?

**SheeEttin** · Mar 22, 2007, 01:18 PM

Re: [partially solved] Feisty can't find CDROM and DVD writer

I suggest filing a bug report over at Launchpad.
Please include a link to the bug report you filed at bugzilla.kernel.org! It'll be very helpful to the guys at Launchpad.

I did it, thanks. Let's wait
