All too soon the pleasant experience with 3.14 was blown away by
3.15 with all its troubles. I can't say 3.14 was stable running omen.com
because it went away so quickly, replaced by the rather unstable 3.15.
Omen.com is back to Heisenbug.
I cannot get my office machine with 3.15 into X. I can press CAPS LOCK
and see the light come on, then the keyboard and mouse are dead.
With a dead machine there is no way to pull data for a crash report.
Not on real hardware anyway.

I have your same problem too, and journatctl says it's NetworkManager just

Thanks for reporting it. It's not necessarily the same issue, though, so
Chuck should check his separately. Of course many things can prevent the
system booting properly.
This is a very unstable point of the kernel cycle, remember: these
kernels aren't even rc1 yet. So it's not unexpected that there might be
problems, and of course they should be reported upstream. Chuck, if your
reference to 'running omen.com' is what I think it is, it's probably a
bad idea to be running Rawhide kernels on a production machine - it's
great to test Rawhide, but we do recommend doing it on a test box...

Yes, of course, I was just giving my two cents as Chuck's incident looked (so)
similar as mine.

In fact, I'm running Rawhide in a computer I could live without - updates-
testing in a more production-like box. It was a kind surprise seeing that rc0
but I also monitor LKML and I know things are pretty unstable.

rc0.git9.1 boots and runs KDE here on a 2.6GHz P4 Dell, but it's definitely a

Same here. Also just running KDE.
The sluggishness is probably due to running debug kernel.

SLUB, not slug! :)
Do you really want to compare Rawhide kernels and Fedora Current
Supported Releases kernels, especially with "Turn on SLUB_DEBUG",
= 3.15.0-0.rc0.git1.1 (v3.14-313-g918d80a13643). :)

Saturday's Rawhide - Creative&Dev plus Xfce seems to be running fine
on an older 8GB mobo and E8500.
I could not get Saturday's rawhide to work on my office machine,
a 32 GB i7-3770K
Rawhide did run on my server, a 32GB i5-3550 but became
unusuable unstable with the update to 3.15.
So there seems to be a progression. 3.15 runs fine on an 8 year old
chip, not so well on newer CPUs.

slub debugging is enabled this early in the kernel cycle. You'll want to
boot with slub_debug=- .

In my VirtualBox Rawhide VM, I have that set, but find that it's almost
useless (I haven't done actual timings to see if it's totally useless, or
just close). The only way I can get reasonable speed is by sticking to
non-debug kernels.
