tmpfs deadlock on stable/9

[Dmitry Morozovsky]

Dear colleagues,

I have ports tinderbox runnign on stable/9-amd64, with working directories on 
tmpfs. I have two consecutive tmpfs deadlocks like

root at beaver:/usr/local/tb/scripts# ps t2
  PID  TT  STAT    TIME COMMAND
 2337   2  Is   0:00.04 /bin/tcsh  
 3079   2  I    0:00.01 sudo -sE   
 3260   2  I    0:00.02 /bin/tcsh  
20309   2  I+   0:00.06 /bin/sh ./tc tinderbuild -nullfs -norebuild -b 
9-i386-RiNet
27035   2  S+   0:00.13 make PACKAGES=/usr/local/tb/packages/9-i386-RiNet -k 
-j1 all
46470   2  I+   0:00.00 sh -ev
46471   2  I+   0:00.01 /bin/sh /usr/local/tb/scripts/lib/portbuild 
9-i386-RiNet 9-i386 RiNet -nullfs gsm-1.0.13.tbz /usr/ports/audio/gsm
46677   2  I+   0:00.00 /bin/sh /buildscript /usr/ports/audio/gsm 2
46766   2  I+   0:00.00 /pnohang 7200 /tmp/make.log4 gsm-1.0.13 make build
46767   2  I+   0:00.02 make build
46768   2  I+   0:00.00 /pnohang 7200 /tmp/make.log4 gsm-1.0.13 make build
46789   2  I+   0:00.00 [sh]
46790   2  D+   0:00.01 make -f Makefile -j4 all
46918   2  I+   0:00.00 sh -ev
46926   2  I+   0:00.00 sh -ev
46928   2  Z+   0:00.09 <defunct>
46938   2  D+   0:00.00 mv gsm_create.o ./src/gsm_create.o
46940   2  D+   0:00.00 mv gsm_print.o ./src/gsm_print.o

(this is parallel build, last 2 rm's are deadlocked on tmpfs) 

what kind of additional info should I send? I have debugging turned on in 
kernel, if it's needed.

Thanks!
