 There might be different problems at play here, one is the mii workqueue
 not being destroyed, but there is another issue apparently:
 
 tc-so:Executing command [ /bin/sh -c env LD_PRELOAD=/usr/lib/librumphijack.so     RUMPHIJACK=path=/rump,socket=all:nolocal,sysctl=yes pppoectl pppoe0 myauthproto=chap                              'myauthname=foobar%baz.com@localhost'                                     'myauthsecret=oink'                                     'hisauthproto=none' ]
 tc-so:Executing command [ rump.ifconfig pppoe0 up ]
 tc-so:Executing command [ rump.ping -c 1 -w 3 10.3.3.1 ]
 tc-so:Executing command [ rump.ifconfig pppoe0 down ]
 
 
 and at that point the client hangs, untill timeout hits. At this moment there
 are two rump_server processes running (with the pppoe connection between
 them), and both do not like attaching gdb (at least on some architectures):
 
 Attaching to process 1853
 [ 2700.9295367] sorry, pid 1853 was killed: orphaned traced process
 Segmentation fault (core dumped)
 
 (and I get a gdb.core, plus the test continues)
