This sounds similar to bug #823146.  Does the system work properly if
you add "modprobe.blacklist=sp5100_tco" to the kernel command line?

Ben.

Bug#822651: linux-image-4.5.0-1-amd64: Spews into /dev/kmsg, causing unresponsive journald

[Ben Longbons]

Package: src:linux
Version: 4.5.1-1
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

Apologies for not following the instructions to run the kernel while
reporting the bug, but the system was barely responsive enough for me to
extract any info.

Whenever my system is started with the 4.5 kernel, systemd-journald uses
about 120% CPU and still complains about dropping messages.

The 4.4 kernel works properly.

I managed to get coredumps of journald every 10 seconds for the whole
3-minute period it was allowed to run, but I doubt it will be useful
given the `dmesg` output.

** Kernel log: (manually saved from previous boot, limited lines because
just running `dmesg` would never stop).
