Well, what do you know, I checked out the commit before Len's ACPI pull request:
git checkout a335750b9a039a9d4cd727cdccacfb90fd63c4e8~1
I.e., the tree I'm currently testing has
commit 10f3cb41d48ab30f5c754b30eea557371892b4c2

Merge git://git.samba.org/sfrench/cifs-2.6
at its top and the mux controller resumes fine:

IOW, I've cut off the tree before the merge commit below, now I have to
go over those patches and see which one is the offender. Stay tuned.

Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux
Pull ACPI & Power Management changes from Len Brown:
- ACPI 5.0 after-ripples, ACPICA/Linux divergence cleanup
- cpuidle evolving, more ARM use
- thermal sub-system evolving, ditto
- assorted other PM bits
Fix up conflicts in various cpuidle implementations due to ARM cpuidle
cleanups (ARM at91 self-refresh and cpu idle code rewritten into
"standby" in asm conflicting with the consolidation of cpuidle time
keeping), trivial SH include file context conflict and RCU tracing fixes
in generic code.
