First thing I did is to see if my drives are /dev/sdX or /dev/hdX, and they are still /dev/sdX...so did a What's wrong with having drives named as /dev/sdX ? Historically SCSI drives were named /dev/sdX, while IDE /dev/hdX. Since some time ago any hard drive is named /dev/sdX regardless whether its IDE/ATA, IDE/SATA or SCSI, there is one uniform interface. l...@home:~$ sudo hdparm -c1 /dev/sda /dev/sda: setting 32-bit IO_support flag to 1 HDIO_SET_32BIT failed: Invalid argument IO_support = 0 (default) Mind that hdparm is a tool which was tailored towards IDE drives only. It is compatible with old interface (/dev/hdX) but only partially with the new one (/dev/sdX). So, is there anything I need to do to make my system change the drives from /dev/sdX to /dev/hdX? There is no point in doing that. Also, right this second, which is being used right this second? ata_generic or pata_ali? How can I verify which is in use right now? dmesg will give you all the information you need. It displays kernel messages (additionally they go to /var/log directory). So you can open a terminal and try: dmesg | less to browse through all the messages. If you want to find out what mode the hard drive is switched to search (to search press /) for lines starting with: ata1 (for the 1st controller) or ata2 (second). In my case I have [0.517229] ata1.00: ATA-7: Maxtor 6L200P0, BAH41G10, max UDMA/133 ... a few more lines here [0.572323] ata1.01: ATA-6: WDC WD1200JB-00GVA0, 08.02D08, max UDMA/100 ... a few more lines here [0.572362] ata1.00: configured for UDMA/133 [0.572365] ata1.01: configured for UDMA/100 Which says what respective DMA modes are enabled for my hard drives.

The change you made is permanent, regardless of the updates. I dont know if this matters, but I am using Prelink and Preload. No It doesn't.

Switching to ata_generic instead of pata_ali... Okay, where are these things... I have sata drives. Okay, so if I wanna try this change, how do I go about doing it? You can omit the first step, because I already know how to open a terminal window! My drives do not show up as /dev/hdX they show up as /dev/sdX, you prob know that, and this could be the symptom of not having and being able to enable 32-bit IO. I read an earlier reply, might have been yours Igor, where trying this change might screw the pooch and render your ubuntu inopperable and it did for the person posting that reply... What about if pop in a different hard drive (a IDE one) or just create another partition on my existing SATA so that I can install a fresh copy of Karmic, just so I can TEST out changing to the ata_generic...if it works in there, then it should be fine for me to do it to my real installation of karmic right?

So do I follow those instructions in that earlier reply where the dude screwed the pooch? And see if it works in a new install, and if so, perform those steps to my real existing karmic?

[Bug 228302] Re: [HARDY-LUCID] No DMA nor 32bits IO support
Hey Igor, why do you say that my bug is prob a new bug? I am experiencing the same as everyone in this bug... I too am at 16-bit IO, without UltraDMA, and when I try enabling 32-bit IO I get the same ioctl error... The only diff is people are reporting this bug with hardy-fiesty etc etc, and karmic, and now lucid... I am using Karmic...my hardware may be new...but I'll tell you a secret, I am not using 32-bit IO and I cannot enable it... And it sounds like I would have to re-write Karmic just to enable 32-bit IO. Also which I did not mention, I have a laptop as well and its not spanking new, it may be 2002 or 2004...and I am using 16-bit IO without UDMA in this as well. I may not be a rocket scientist, but I have come to the conclusion that Karmic came out in late 2009, and my laptop came out in 2002 maybe 2004...so I would say Karmic should be BETTER than my laptop. But its not...Karmic cannot fully utilize the massive technological power of the hardware that's being developed now in 2002 or 2004...er, uhm, I mean if you took a copy of Karmic and travelled back to 2002 or 2004, then my last statement makes, er, sense. You know its 2010...and 25 years ago we had 16-bit IO...and you should have seen the pieces of crap that had 16-bit IO. I predicted new OS after new OS will come out, and we'll still be at 16-bit IO. I am a bit like Nostradamus then! And I predict that there are thousands out there maybe more, yea prob more... fiesty, hardy, karmic, lucid who are at 16-bit and don't even know it! So then this is our little secret... The switch over to Ubuntu slogan should be changed to...UBUNTU! - 1982 brought that 8-bit computer, Commodore 64, faster than one of those... UBUNTU! - And remember in 1985 came the 16-bit Commodore Amiga! Now, welcome to 2010... UBUNTU is more processing power than an Amiga yet preserving the same drive IO access speeds! There's gotta be 1 unemployed programmer somewhere...we just gotta find him and we'll do a collection and we'll pay him for an hours work just to repair this bug. Unless of course, you've found him already, and thats why this bug has been around for OVER 2 years, because he knows once he's fixed this bug he will have outlived his usefulness!!! Can we request Ubuntu, that whenever they finally do release a 32-bit version, they stipulate it in the download name, like for example: Ubuntu 10.4 Lucid 32-bit IO.rar...or even change current ones...Ubuntu 10.4 Lucid 16-bit IO.rar and Ubuntu 10.4 Lucid 8-bit IO (if they invented that)!

weird, I tried to use apport-collect 228302 and it wouldn't let me add
to this bug. So, here's my situation.
I'm successfully running hardy on another partition with snappy response
and ability to play dvd's.
I have a fresh install of lucid on another partition. I had to go to
icewm because gnome, kde, xfce are too slow. I cannot play dvd's without
blurry, dropped frames, etc.
So, finding this bug, I tried enabling ata_generic and blacklist pata-
ali. With this, I can boot up but it takes several minutes. And, once
up, the dvd is not recognized. dmesg shows:

I decided to try the maverick kernel from the kernel ppa, and it does
the same thing. In fact, that's what I'm using now.
Any ideas how to fix this?
Since I don't seem to be able to use apport add my stuff, let me know
what I need to post.

Igor, I really appreciate the efforts you're putting into solving this bug, however I think the changes you made to Lucid kernel brought different troubles to my system (Uli M1575 chipset), forcing me to file bug #591532 . The reason why I think that bug is related to this one is because: 1) I'm affected by this bug since Feisty 2) The DMA errors I get in bug #591532 started appearing with Lucid 3) The changes you committed to Lucid kernel strongly affect my hardware 4) If I follow Antonio O.'s tips about ata_generic, I don't get those errors (but I've double-checked with `hdparm -tT /dev/sdX` and write/read speed is really slow compared to pata_ali, I would say it's halved) Please, I would really appreciate if you could have a look that bug, because I need to understand the source of those errors, and if you confirm it's really related to this bug, it would be one goal for me and for anybody affected by the same bug.

Igor, I thought the only pata_ali changes were made by Andy, that's why I thought it could be the reason.

As regards this bug, I'm really happy I can now easily load/unload pata_ali as a module on Lucid thanks to Andy's efforts, but since I'm stuck with a disappoining A8R-MVP (which doesn't even let me have a working 64bit os with hardware memory hole, by the way) with a buggy chipset, ata_generic is not helping that much...

Hi guys and thank you everybody for your support. I solved with my pata_sis in a very basic way, perhaps not very orthodox: I started my s.o. with this (grub) command line: ... ata_generic.all_generic_ide=1 libata.fake_parm=0 It caused libata, pata_sis and pata_acpi fail in module loading. Once my system mounted any hard-disk partitions as hda instead of sda then I added a grub line with that expedient to my grub menu.

From the kernel-parameters.txt documentation I noticed it says the following: Module parameters for modules that are built into the kernel image are specified on the kernel command line with the module name plus '.' plus parameter name, with '=' and value if appropriate [...] Therefore, the parameter we should use is: ata_generic.all_generic_ide=1 So, this is how to get it working: 1. Add blacklist pata_ali to /etc/modprobe.d/blacklist 2. Run sudo update-initramfs -u 3. Add ata_generic.all_generic_ide=1 to the GRUB_CMDLINE_LINUX line in /etc/default/grub 4. Run sudo update-grub 5. Reboot (preferably using the recovery option so that you can see the verbose boot information). WARNING: the above instructions may render your system unbootable (as it did for myself). If that happens, you will need to boot from a live CD, chroot into your installation and undo the blacklisting of the pata_ali module. If you're not comfortable with this risk, then don't follow the steps above. Unfortunately, this still doesn't solve the problem for me, as the ata_generic driver refuses to work with my hard drive (spewing DMA errors). If I can find some way to make the kernel assign the pata_ali to ATA port 1 (my hard disk) and ata_generic to ATA port 2 (CD-ROM), perhaps that would work. If anyone has suggestions, let me know.

I've double checked current lucid kernel linux- image-2.6.32-21-generic_2.6.32-21.32 and it seems that it is not fixed! There is no ata_generic.ko there. So ALI owners will still suffer from disabled DMA!

[Bug 228302] Re: [HARDY-LUCID] No DMA nor 32bits IO support
Andy, I noticed that you re-modularized the PATA/SATA drivers in kernel 2.6.32-17.26. Unfortunately, you forgot to re-modularize the ata_generic module as well. I tried blacklisting the pata_ali driver and booting with all_generic_ide, but no hard drives or ATAPI drives were detected, and I was booted to the initramfs shell. I suspect that the boot option isn't parsed because the ata_generic module is still built- in to the kernel. ... or perhaps the option has been renamed; I'll do some experimenting and try to find out. -- [HARDY-LUCID] No DMA nor 32bits IO support https://bugs.launchpad.net/bugs/228302 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 228302] Re: [HARDY-LUCID] No DMA nor 32bits IO support
By the way, I'm not sure that some ALI chipsets are buggy. If ata_generic works fine, and pata_ali does not it would point at a bug in the pata_ali driver. But it's just my thought - I haven't investigated the kernel sources or the chipset itself. -- [HARDY-LUCID] No DMA nor 32bits IO support https://bugs.launchpad.net/bugs/228302 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 228302] Re: [HARDY-LUCID] No DMA nor 32bits IO support
Montblanc. I'm not sure of what kind of 'full speed writting' you are talking about. My observation is that pata_ali DOES NOT WORK properly with CD/DVD drives. Burinig a disck using pata_ali is hardly possible, takes 100% cpu and takes forever since cdrom DMA transfers are disabled. Enabling DMA through /sys makes reading/writting impossible (errors). Using ata_generic instead of pata_ali solves all the problems. DMA works fine. Current ubuntu kernels prevent the user to choose ata_generic over pata_ali! Regarding possible inferior performance of ata_generic I've discovered that there are none. See attached performance and dmesg results. Files: *.custom hold results for my customized kernel (see post #58) with ata_generic instead of pata_ali driver. Other files hold results for the current Karmic kernel with pata_ali. So there are two possible solutions: 1. somebody fixes pata_ali driver which seems to be broken - mind the warning: WARNING: ATAPI DMA disabled for reliablity issues - it's ridiculous, especially that ata_generic works fine. 2. ubuntu developers prepare the kernel in such a way which allows to use generic_ata driver! which I agree is kind of workaround, but it might be just good enough, and it's way better that the current situation which prevents using a cdrom/dvd drive! -- [HARDY-LUCID] No DMA nor 32bits IO support https://bugs.launchpad.net/bugs/228302 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 228302] Re: [HARDY-LUCID] No DMA nor 32bits IO support
Igor, Let's try to get a summary of action needed. Problem: the pata_ali kernel driver does not support ATAPI DMA transfers properly on certain ALI chipsets (even if force-enabled via the driver option atapi_dma=1). The ata_generic kernel driver supports ATAPI DMA transfers for such chipsets and has a special kernel boot option, all_generic_ide, which causes it to override the manufacturer-specific drivers. However, this option does not work correctly when the ata_generic and pata_ali drivers are compiled-in to the kernel, which means that the ata_generic driver is impossible to use. Solution: Change these kernel config parameters: CONFIG_PATA_ALI=y CONFIG_ATA_GENERIC=y To the following: CONFIG_PATA_ALI=m CONFIG_ATA_GENERIC=m Result: 1. For all other users: there will be no functional difference between the original and modified kernel configuration (as long as the logic to automatically modprobe the ata_generic/pata_ali kernel modules is properly in place) 2. For users with buggy ALI chipsets, they can now take advantage of the kernel boot options all_generic_ide and/or to manually blacklist the pata_ali driver, which will cause the ata_generic driver to be used (and as a result, ATAPI DMA will work properly).

Please, remember: a workaround is NOT a solution. With this workaround, CPU usage is back to normal, but we can't write to full speed and that's really frustrating. The only way to solve this bug is getting Canonical to change its policy about PATA drivers, or just surrender to new Ubuntu versions solving something and screwing up another one. -- [HARDY-LUCID] No DMA nor 32bits IO support https://bugs.launchpad.net/bugs/228302 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
