udev (probably)

I've been working all day rearranging furniture in my apartment. I got
the my computer to its new spot and hooked everything up and booted and
I saw a message that said something about some kernel option that was
turned on that shouldn't be, and that udev might not work. When I got
logged in, I found that Mythtv was all screwed up and that it said I
didn't have any programs set to record. LiveTV didn't work at all. My
tv card (dev/video0); ls says it's there, but cat says it's not. When I
used /etc/init.d/udev I got a message saying that the udev initscript
only works with baselayout 2 and that I shouldn't use it with baselayout
1. I didn't even know I was using baselayout 1! Anyway, is there a
way, after I've booted the computer, to access those messages shown at
startup?

I found it in /var/log/messages. It said:

Nov 23 15:37:07 camille kernel: udev: missing sysfs features; please
update the kernel or disable the kernel's CONFIG_SYSFS_DEPRECATED
option; udev may fail to work correctly
Nov 23 15:00:01 camille sudo: michael : TTY=pts/4 ; PWD=/home/michael ;
USER=root ; COMMAND=/etc/init.d/udev restart

I'm rebuilding the kernel with that option disabled, but in the meantime
why did Mythtv forget my programs set to record? I checked that mysql
is running, and it is, I checked mythbacked. The only discrepancy I can
find is the existence of /dev/video0...

Question one: You using baselayout 2 or 1?

I ran into this the other day and I just recompiled a new kernel with
the CONFIG_SYSFS_DEPRECATED option disabled. It's under the General
Setup screen as:

Create deprecated sysfs layout for older userspace tools

I'm pretty sure that is it. After you disable that and reboot,
everything should go back to normal. I don't have MythTV or anything so
I hope everything will go back to normal on that too.

Hope that helps.

I also had this message for maybe a week before I rebuilt the kernel
(same way as you). The only difference I noticed was that the error
message went away, but maybe it had some effect on your hardware?

Since I hadn't rebooted in a while, I don't know what changed on mine
either. It appears udev was still working tho. I noticed this when I
went to single user and typed in the wrong process number and killed
udev. I restarted it and got the error the OP got. I figured I would
fix it while I was already that close to a shutdown anyway.

I suspect tho that MythTV sort of complicates things by needing udev to
create things not needed on a system without MythTV.

For the record OP, if you are on baselayout-1, you can start udev by
typing in /sbin/udevd --daemon. I'm pretty sure you have to be root to
do that tho.

Re: udev (probably) [In reply to]

The only thing I saw in dmesg that might point to a myth problem was:

ivtv0: Failed to initialize on minor 32
ivtv0: Failed to initialize on minor 64
ivtv0: Failed to initialize on minor 224
ivtv0: Failed to initialize on minor 0
ivtv0: Failed to initialize on minor 24
ivtv0: Failed to initialize on minor 0

Re: udev (probably) [In reply to]

Add
>=sys-apps/baselayout-1.12.13
to your /etc/portage/package.mask and
emerge -DuN world
and reboot the PC

It worked for me. There is also a bug in bugzilla with more solutions:
http://bugs.gentoo.org/show_bug.cgi?id=291916

For the first message you can turn

CONFIG_SYSFS_DEPRECATED

off in your kernel but it has nothing to do with the problem....

If MythTV can't find your TV card, it can't record from it and gives the
slightly ambiguous message about no programs to record. It is true,
because without a configured input, it won't record any programs.

Is it possible to be totally partial?

I build kernel 2.6.30-r10 and booted with it and Myth seems to work fine
now...
