ureadahead is incompatible with newer kernels

[Cedric Schieli]

When booting the backported kernel image from linux-lts-raring, tracing is failing with the following error:
ureadahead: Error while tracing: No such file or directory

This is due to the removal of the obsolete tracing_enabled interface. This has been handled for Raring in package version 0.100.0-13 (bug #1085766).

A simple backport of this package fixes the issue for me.

Status changed to 'Confirmed' because the bug affects multiple users.

The backport from your ppa works for me. I think you should add your patch here.

Here is the patch used in my PPA.

The attachment "use_tracing_on_instead_of_tracing_enabled.diff" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

Is this fixed now? I see no issues here.

[Cedric Schieli (cschieli)]

I'm now running the kernel from linux-image-generic-lts-saucy and the issue is still present.

I've just reverted my patched ureadahead from my PPA to the stock one (which is still the same version as when I've opened this bug), removed the pack files from /var/lib/ureadahead and rebooted. No pack files got created.

Reverting now to my patched version.

Now I see it. Could you share the PPA URL? I can't find it through your profile. Thanks.

Never mind, found it:

Just to confirm: your PPA package works fine here too. On Saucy HWE (cannot use Trusty for other reasons).
