Bug Description

Lucid SRU Justification:
Impact: In Karmic the ahci driver was built in by default in the kernel. However, in Lucid, this driver is now enabled as a module. Refer to:

commit 99380e40c725fbb737e1fbf30c9c54e4c6285455
Author: Andy Whitcroft <email address hidden>
Date: Tue Feb 9 16:07:33 2010 +0000

    UBUNTU: [Config] de-modularise SATA disk controllers

As a result we need to add the ahci module to the virtual sub-flavour .

Install the virtual kernel package and confirm virtualbox guests using virtual sata drives within virtualbox do not boot properly. Install the updated virtual kernel flavor and confirm virtualbox guests using virtual sata drives within virtualbox are now able to boot.


The linux-image-2.6.32-21-virtual kernel package does not include the ahci module:

  $ dpkg-deb -c linux-image-2.6.32-21-virtual_2.6.32-21.32_amd64.deb | grep ahci

this is unfortunately the driver that virtualbox guests need to use virtual sata devices (rather than ide) within virtualbox, meaning that virtualbox guests with the virtual kernel installed won't boot. Installing the ahci.ko from the corresponding linux-image-2.6.32-21-server kernel and updating depmod and the initramfs lets the system boot under virtualbox.

(It doesn't look to be a regression from karmic, as that version's virtual kernel also didn't include the ahci, though I haven't tested it for sure -- it's possible ahci could have been a built-in module).

Hi Steve,

Indeed this indeed looks like this was built in for Karmic and only enabled as a module for Lucid. We'll try to get this fixed up in a Lucid SRU. Thanks.

Hi Steve,

I quickly built a test package which has added the ahci driver to the virtual flavour.

$ dpkg-deb -c linux-image-2.6.32-22-virtual_2.6.32-22.33~lp570542v1_amd64.deb | grep 'ahci'
-rw-r--r-- root/root 77856 2010-04-27 13:23 ./lib/modules/2.6.32-22-server/kernel/drivers/ata/ahci.ko

I've also sent the patch to the Ubuntu kernel-team mailing list and have received the required number of Ack's for getting this approved as a Lucid SRU:

Hi Leann,

I've tested the kernel you posted at and can confirm that it boots within virtualbox.

Is there a timescale for this fix to be released?

I have updated my x86 Ubuntu 10.04 VirtualBox guest this morning with all the currently available updates and it doesn't appear to fix this issue as it still only boots from IDE and not SATA.

$ dpkg-deb -c linux-image-2.6.32-22-virtual_2.6.32-22.36_i386.deb | grep ahci
tar: Record size = 8 blocks

Is it possible to get an interim kernel build for x86 rather than AMD64?

Accepted linux into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See for documentation how to enable and use -proposed. Thank you in advance!

The patch to fix this issue is already incorporated into the Maverick kernel. I'm therefore marking the Maverick task as Fix Released. Thanks.

I have also run the kernel regression tests from the lp:qa-regression-testing bzr tree which showed no regressions for any of its tests.

Marking verification-done.

Stupid question: how can I get the fixed kernel into the machine that I cannot boot without any major pain? Or where do I get an updated ISO-image of ubuntu-10.04-server?

I have upgraded my Ubuntu installation in my VirtualBox environment from 10.4LTS to 10.10 and this bug has reappeared with the following message:

FATAL: Error inserting ahci (/lib/modules/2.6.35-22-virtual/kernel/drivers/ata/ahci.ko): Unknown symbol in module, or unknown parameter.


The Loeki (the-loeki) wrote :

I second that.
Both upgrade and clean install result in same error as Andy.

Got hit by #659084 at the same time.
The two issues seem to have some similarities between them in that they're both broken kernel modules in the -virtual that should've been available and seem to have been compiled in, or the build at least should've tried.

I've noticed that the -headers packages contain the same files overall, but the -image-virtual packages are missing both libahci.ko and the mentioned .ko's in #659084.

With the bug re-appearing in Maverick final, and persisting, shouldn't this bug be re-opened for Maverick current? The problem remains up to, and including the latest 2.6.35-24-virtual kernel.

Examining the contents of the debs, the module is available in the latest Lucid, Maverick, Natty, and Oneiric -virtual kernel flavors.

I just tried with 11.04 in Virtual Box.
The module is included but it doesn't work. Dmesg shows lots of ahci: Unknown symbol errors. See bug #658461 which is marked as a duplicate of this one.

Please reopen. Seems to require libahci.ko in addition to ahci.ko in order to resolve this bug.

The Loeki (the-loeki) wrote :

The ahci.ko needs libahci to work, which is included in linux-image-extra-virtual (along with everything but the kitchen sink). It *SHOULD* be included in linux-image-virtual IMHO, because ahci.ko is next to worthless without it, and installing an additional 120MB of drivers, modules and cruft to get a 47KiB module to get SATA to work is just plain silly (bug #658461)

Workaround (I guarantee nothing :-P ):
cd /tmp
apt-get download linux-image-extra-3.0.0-12-virtual
cd /
dpkg --fsys-tarfile /tmp/linux-image-extra-3.0.0-12-virtual*.deb | tar --wildcards -xf - */libahci.ko
depmod -a
update-initramfs -u
shutdown -r now


The Loeki (the-loeki) wrote :

On a side note, something appears not right there anyways;
modules.dep doesn't list libahci.ko as a dependency for ahci.ko, while modinfo does
so either depmod -a silently fails the dependency and doesn't list it, or something strange is going on with the dependency resolution.

Michael Bloom (mabloom) wrote :

Well I THOUGHT I was preparing to use virtualbox on oneiric when I apparently downloaded that virtual kernel. Now the system I was going to use as host is failing to boot with those ahci: unknown symbol messages, as well as getting "HDIO_GET_IDENTITY failed for /dev/sda: Invalid Argument" messages.

How do you get the workaround above to work when the host won't boot?

Michael Bloom (mabloom) wrote :

I had written: "How do you get the workaround above to work when the host won't boot?"

Duh! I just had to scroll down to the generics that were just off screen, so now I can install the workaround.

Selecting the package "linux-virtual" fortunately does not de-install linux-generic, but it does cause the host system's grub config to be updated to boot linux-virtual by default.

Was the current linux-virtual released without first trying to boot a host system? If someone had tried a simple "reboot" after installing linux-virtual, they would have noticed that the host could no longer boot! Unless they had manually installed the "workaround" as well, simply "knowing" that it was needed rather than relying on the dependency mwechanism.

Someone will probably respond that you are not supposed to install linux-virtual on a host machine. And it's probably even documented somewhere. But if that's the case, shouldn't there be some check performed to prevent (or at least warn about) it's installation on a host machine?

I've built test kernels for Natty 11.04 and Oneiric 11.10 which add the libahci driver to the virtual kernel flavor. Please test and let me know your results, I can then submit this for a Stable Release Update for the Natty and Oneiric releases. For Precise 12.04 this should be a non issue as the ahci and libahci drivers are built in for Precise (ie CONFIG_SATA_AHCI=y). Thanks.
