[fedora-arm] F17 rootfs on Trim Slice = kernel problems

[Richard W.M. Jones]

I tried the rootfs posted here:

http://fedora.roving-it.com/rootfs-f17-hfp-alpha1.tar.bz2

on a Trim Slice.  However the included kernel
(3.3.0-0.rc4.git3.1.fc17.armv7hl.tegra) gives lots of errors like
this:

[  572.198943] BUG: sleeping function called from invalid context at include/linux/freezer.h:46
[  572.207448] in_atomic(): 0, irqs_disabled(): 128, pid: 538, name: bash

This breaks every process (not just bash), so not much works.  I've no
idea why it's trying to suspend.

There's apparently a patch that fixes this:

http://lists.infradead.org/pipermail/linux-arm-kernel/2012-January/079842.html

However I cannot at the moment test it because I don't have a
cross-compiler setup.  Surely I can't be the only one seeing these
failures?
