Kernel oops when inserting pcmcia CF reader

Additional info: output of lshal. uname, udev ect, ls -l /dev/sd* returned empty list, gvm log is alsa empty

s/alsa/also

Output of pccardctl with different options. It seems that CF card is identified but not mounted.

> I must say that I've not seen this bug in Debian 4.0 and openSUSE 10.2 (both have 2.6.18 kernel) so I think this bug is specific to Ubuntu.

It looks not logically for me. Ubumtu 6.10 have kernel-2.6.17; Ubumtu 7.04 kernel 2.6.20. This all distributions not comparable. Did all tested distributions are amd64 ? Have you tried latest git of vanilla_kernel ?

I looks like libata specific bug, and libatas pata support is highly experimental.
Take a look to this bug http://bugzilla.kernel.org/show_bug.cgi?id=7711

I think the best way to get it fixed is upstream.

> Did all tested distributions are amd64 ?

Yes teseted distros were amd64.

> Have you tried latest git of vanilla_kernel ?

No I have not, all kernels were default kernels that come with distributions, no 3d party patches applied or self-compiled kernels used.

Maybe they (tested distros) have ATA support disabled in kernel, or use ide-cs instead of pata_pcmcia, I don't know. Unfortunately I have no access to dmesg of tested distros (I simply deinstalled them) to prove it. I can try to install Debian on a separate partition on weekend and post some debug info if needed.

Is there any way to disable pata_pcmcia support, for example blacklist it and use ide-cs instead?

No.

Ubuntu kernel do not have this module.

You don't need to install debian on your system to test or fix it.

Possible solutions:
1. ask ubuntu-kernel-team to include this module. because i think libata
module will not be fixed on ubuntu.
2. try vanilla kernel,( www.kernel.org ) and if it's not fixed fill a
bug at bugzilla.kernel.org and ask to fix it, they will do it ;) -- the
best choice!!! after this it will be included in the next release in
any distr.

Thanx for reply.

Well, quick investigationn of packages.debian.org shows that there is now ata support in their kernel instead they use ide-cs, so this is why CF worked in debian.

Ok I'll try to fill a bug at bugzilla.kernel.org, and use an usb multicard reader :) If any pacth will be introduced will it be backported by ubuntu kernel team? As I understand the module will be fixed in the latest kernel (2.6.22 or whatever)?

Hello!

I've made an experiment: downloaded and burned i386 version of Feisty, booted from CD and magic happened! CompactFlash mounted perfectly! I've attached corresponding dmesg part. So what are your suggestions? Is it a packaging problem?

PS. I'm very close to switching to i386 distro :)

No! It looks like kernel_64bit problem.
You can go windows-user way and install other distro.
Or linux-user way and fix this issue and make 64bit_kernel more stable
;) Remember awry thing what working was done with somebody's help, you
can help other too.

Ok I'll stay with this one, :) you are right! Nevertheless here is corresponding bug report at bugzilla.kernel.org http://bugzilla.kernel.org/show_bug.cgi?id=8424

Andrew Morton paid attention to it - it's a good sign. :)

I'm hit by exactly the same bug on my Dell D820 with the 64-bit version of Edgy. It's really annoying because it really mean I have no way to use that CF card in my laptop at all. Bug occurs 100% of the time, so it's quite serious. I can attach the dmesg, but it's fairly similar to the one above.

it seems to be fixed for gutsy. Please try.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

This problem was fixed in later kernels. If there is an issue with current kernels, please submit a new bug report.
