I haven't been able to boot the last 3 Rawhide kernels,
kernel-3.4.0-0.rc3.gitX.1.fc18.x86_64, where X = 2, 3, 4. The kernel
with X = 1 boots fine. When I try to boot the other 3, I get dropped
into a debug shell with dracut complaining about being unable to find
various devices. Today I got around to trying to figure out why.
Manually running "new-kernel-pkg --package kernel --mkinitrd --dracut
--depmod --update 3.4.0-0.rc3.git4.1.fc18.x86_64" spewed a large
number of lines like this:

In the working kernel (X = 1), these symbols are provided by
/lib/modules/3.4.0-0.rc3.git1.1.fc18.x86_64/kernel/net/llc/llc.ko. On
the broken kernels, the llc directory is still there, but it is empty.
What happened to the llc module? The pps_core module
(kernel/drivers/pps/pps_core.ko) has also gone missing in the more
recent kernels, accounting for still more unknown symbols. I ran "rpm
-V" on the recent kernel packages and just got the expected:
.......T. /lib/modules/3.4.0-0.rc3.git4.1.fc18.x86_64/modules.devname
.......T. /lib/modules/3.4.0-0.rc3.git4.1.fc18.x86_64/modules.softdep
Have I done something wrong, or are the recent kernels busted?
I built libguestfs today, which as part of the Koji build will boot
and run the current kernel. It *didn't* fail, indicating that the
kernel is good. Here are the build logs if you want to look further:
http://kojipkgs.fedoraproject.org/packages/libguestfs/1.17.33/1.fc18/data...
(It might just be a problem confined to 802.x and bridge devices,
which we don't test.)
