Hi all,
I also have this issue with my sparcstation installation :

Emulated OS                             :       SunOS 5.5.1
Emulated Processor                      :       sparc
Host machine OS                 :       Linux RED HAT

Do you manage to fix it ?

  qemu-system-sparc MUTEX_HELD assert and libC lock errors

Status in QEMU:

Bug description:
  Here I am cross-posting a comment I made on Artyom's blog.  Atar
  responded that he "fixed these issues for some customers".  I hoped
  that opening a bug to the opensource project might help develop the
  solution for the public domain.

  I now have a mostly-working Solaris 6 emulation, with great thanks to
  the valuable information in Artyom's blog, brezular.com, and the
  QEMU/Solaris 4.14 wikibook.

  setup detail;
  QEMU (present git snapshot, reports --version 2.2.92)
  -M SS-20, openboot/proprietary prom

  # uname -a
  SunOS emu0 5.6 Generic_105181-33 sun4m sparc SUNW,SPARCstation-20

  I continue to have a problem, which I have found others posted in blog
  comments, but have not seen a resolution yet.

  # /etc/init.d/init.dmi start
  Run-time error, libC:
  Trying to release a lock that was not acquired in this thread
  (repeat above 1x)
  Abort - core dumped

  as well as:
  Assertion failed: MUTEX_HELD(&svc_mutex), file rpc/svc_run.c, line 766

  which prints to the console periodically when "dmispd" is running.
