After my latest 'emerge --sync' and 'emerge -Dp world', came udev-104-r11
which is incompatible with coldplug.

All I could find at the gentoo site is " You no longer need to emerge
coldplug if you're using udev version 103 and higher. If you receive a
message that udev blocks coldplug from being installed, then you don't need
to install coldplug."

Not true. I've installed udev on my mythtv box and it no longer detects
an external USB drive at bootup nor does it detect an external video capture
device (plextor convertx). Kernel is linux-2.6.17 (2.6.18+ broke the
via vt8251 sata support so I can't move past linux-2.6.17 right now)

Any idea how I can get the system to detect my usb devices? In the
meantime, I'll be reverting to the old udev.

Hey!

It may be a silly question, but did you do a revdep-rebuild after updating udev? It's a required
thing is you were using udev <1.*

I didn't; why would it be necessary? AFAIK, The only thing udev does is
create /dev device entries and load kernel modules. I did an 'equery
depends udev' and on my main desktop all I came up with was 'hal' and I
don't have that on the mythtv box that is having the problems.

Because of this:

# equery files udev | egrep "\.(so|a)"
/lib/libvolume_id.so
/lib/libvolume_id.so.0
/lib/libvolume_id.so.0.75.0
/usr/lib/libvolume_id.a
/usr/lib/libvolume_id.so

Strange, that.

That's a file server, too, so I should have noticed the sata support
breaking.

Instead of asking why you should run revdep-rebuild, why don't you
just try it (with -vp) and see what it says? I routinely do that after
every upgrade just to be on the safe side. Might be excessive, but
there's no harm in it.

Just to make sure: did you edit /etc/conf.d/rc, so that RC_COLDPLUG is
set to "yes"? Udev only does autodetection if this variable is set,
according to that file. I completely missed this information at first,
found it by coincidence. Maybe that helps, otherwise I've no clue how to
solve this.

revdep-rebuild didn't help

I did an emerge =udev-87-r1 and an emerge coldplug and ended up with a
system that now saw my usb devices, but lost the loopback network device!
'lo' was missing, 127.0.0.1 was mapped to eth0 and my normal fixed ip
address was mapped to eth0:1. a u r g h. Had to drag out a keyboard for
the first time in a year (this is a mythtv box normally w/out keyboard)

I removed coldplug and reemerged udev and this time it took. /etc/conf.d/rc
had COLDPLUG set. My usb devices were properly detected and the network
is back to normal.

Now if only the kernel.org people would fix bug 7589 and get via vt8251 sata
working again for kernel versions >2.6.18.5.

Interesting. Maybe it's fortunate I've been too lazy to upgrade from
18.1 after all.
