I see two new warnings/errors at booting time:

      Code:
[    0.493386] ERST: Failed to get Error Log Address Range.
Loading, please wait...
modprobe: module unix not found in modules.dep
INIT: version 2.88 booting

Are the ERST and modprobe message something to worry about?

The modprobe warning is a purely cosmetical issue and bears no consequences at all.

Background for this issue is an interaction between kernel, udev and the last busybox upload introducing its own modprobe utility. While the kernel has "unix" (UNIX domain socket support) built in statically, udev's initramfs hook force-loads it (for custom, very rare, kernels that build it modular) - but busybox' new(ly enabled) modprobe implementation complains if it can't load a module, if it's built-in (~=and already loaded), see #652672. UNIX domain socket support is a very basic functionality needed by basically everything in unixoid operating systems, so building it as module makes no sense on "normal" kernels - actually it's not even possible under normal circumstances.

Thank you, slh

P.S: I had a different ERST error before with the 2.6.3x kernels
