udev 146-5 and ppc64 kernel

Hi,

My quad-G5 is not updatable anymore (on Debian-testing) because udev
fails to install.

Here is the message :

marie:/home/luigi# LANG=C apt-get -f install

Preparing to replace udev 0.141-2 (using .../udev_146-5_powerpc.deb) ...
Since release 146, udev requires support for the following features in
the running kernel:

- inotify(2) (CONFIG_INOTIFY_USER)
- signalfd(2) (CONFIG_SIGNALFD)

Please upgrade your kernel before or while upgrading udev.

dpkg: error processing /var/cache/apt/archives/udev_146-5_powerpc.deb
(--unpack):
subprocess new pre-installation script returned error exit status 1
Errors were encountered while processing:
/var/cache/apt/archives/udev_146-5_powerpc.deb

Nonetheless both inotify and signalfd seems to be activated in the
running kernel:

marie:/home/luigi# grep -i inotify /boot/config-2.6.30-2-powerpc64
CONFIG_INOTIFY=y
CONFIG_INOTIFY_USER=y
marie:/home/luigi# grep -i signalfd /boot/config-2.6.30-2-powerpc64
CONFIG_SIGNALFD=y


and of course:

marie:/home/luigi# uname -a
Linux marie 2.6.30-2-powerpc64 #1 SMP Sun Oct 4 09:29:28 UTC 2009 ppc64
GNU/Linux

Moreover it worth noting that even /proc shows that at least inotify
seems to be activated:

marie:/home/luigi# ls -ld /proc/sys/fs/inotify
dr-xr-xr-x 0 root root 0 oct 19 10:23 /proc/sys/fs/inotify
marie:/home/luigi# ls -l /proc/sys/fs/inotify
total 0
-rw-r--r-- 1 root root 0 oct 21 21:13 max_queued_events
-rw-r--r-- 1 root root 0 oct 21 21:13 max_user_instances
-rw-r--r-- 1 root root 0 oct 21 21:13 max_user_watches

I don't know how to check for signalfd.

Another Debian user may have been hit by this (but no follow up that I
am aware of):

http://forums.debian.net/viewtopic.php?f=5&t=46128&start=0

So I guess I am not the only one but the bug doesn't seems to be
reported (yet):
http://bugs.debian.org/cgi-bin/pkgreport.cgi?which=src&data=udev&pend-...=fixed&

Any idea that I may be missing before filling a bug report?

udev's preinst checks for those features by looking for
sys_inotify_init and sys_signalfd in /proc/kallsyms.

Look at the preinst script and check your system; you should find
pretty quickly what's wrong with your system/config or udev.
