ureadahead needs an out-of-tree kernel patch to add trace events for
open(), exec() and uselib() syscalls that take file paths, see bug
462111. This needs to be changed to use fanotify() which is available in
the standard kernels. However, it needs to be checked whether it's also
available on the
So, is this a problem of the 4.0 kernel itself or the kernel
configuration?

Yes, I had the same.
I traced it back to the following:
Before and after the upgrade to 15.04 I was running kernel 4.0 (same as
reporter). Apparently with this kernel something doesn't want to trace
(whatever that means in this context). As a result no 'pack' file is generated
in
Looks like that other bug still exist, and should grab some more attention as
tracing cant be done:

Cristian, sorry I had been on vac for two weeks. For ssh you either need
to be able to ssh to a public host where I can ssh to as well (a server
of your's, a cloud instance, etc.) and forward your port 22, as you are
behind a NATed network. Or open port 22 on your router; but I guess that
isn't

OK, no *.pack files then, so the problem is on the initial data
collection. Can you please run
sudo ureadahead --verbose /tmp/output 21
in a terminal, then do some file system activity (e. g. cat /bin/bash
/dev/null), then press Control-C, let it finish, and attach
/tmp/output?

You
All Right?

Hm, that's veeery terse, there should have been multiple screenfuls of
output. But still no error message. Is it possible to get ssh access to
your system? I don't know what happens with ureadahead on that
particular one.. :-/ This needs stracing, gdb'ing, etc., and that's
really hard to do
