Fix reference return value of dir method in Net::FTP [TODO]
Mon, 15 Oct 2007
From Net::FTP manpage:
dir ( [ DIR ] )
Get a directory listing of "DIR", or the current directory
in long format.
In an array context, returns a list of lines returned from
the server. In a scalar context, returns a reference to a list.
In some situations, it returns undef in array context, it should probably return a reference to an empty array instead.

Check if iurt needs a specific timeout for dkms packages [TODO]
Mon, 15 Oct 2007
Sometimes, the iurt process rebuilding dkms is killed, check if it's because we need to set a specific timeout for dkms rebuilds.
Our udev rules modprobing usblp are outdated, they are leftovers from the hotplug migration, when the required aliases where not in the kernel yet.
This is probably the same for a lot of modules in /etc/udev/rules.d/70-hotplug_map.rules.

Fix X crash in Mesa when glxinfo is run without DRI [TODO]
Mon, 15 Oct 2007
When glxinfo is run on displays without DRI, it sometimes makes the X server crash (backtrace incriminates the _mesa_initialize_context function).
This is currently workarounded in drak3d by blacklisting known drivers on which it crashes, but it should be properly fixed in Mesa.

Fix assigning gov of 0x01 to cpuFreq
fbmenu (from bootsplash package) is used to show a graphical netprofile menu early in boot. It is currently built with gtk-linux-fb, which is unmaintained and deprecated.
We should package gtk-directfb, and cairo-directfb (since the former requires it).
The patch in bootsplash is quite trivial.

The network scripts send message over DBus on interface events, handle them in the network center.
We could also handle some udev/hal messages on-the-fly (in my dreams).

Disable automatic association in ipw2xxx modules [TODO]
Wed, 22 Aug 2007
Add these in some default modprobe options file:
options ipw2100 associate=0 options ipw2200 associate=0
to prevent automatic association to open access points. We prefer to rely on wpa_supplicant.

Some race during coldplug prevents USB controllers modules from being loaded, they can't find some usbcore symbols at loading time.
https://bugs.launchpad.net/ubuntu/+source/module-init-tools/+bug/24238 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333052
The suggested patches have been applied upstream, so we already have them in the distro. The loop checking module loading status in /proc/modules should have been enough, need to investigate more.
Debian lowered the bug importance not to block their final release, and the bug was eventually marked as fixed later, without valuable explanation.

Trying rmmod ehci_hcd; rmmod uhci_hcd; umount /proc/bus/usb; rmmod usbcore; udevtrigger; grep usb /proc/modules to reproduce isn't enough, the bug probably appears only when the system is overloaded.
