Yes, the panic is a result of the earlier warning.  Poul-Henning touched this 
code last, so it is probably something for him to look at.  I'm unsure how 
msleep() is getting called, however.  The turnstile panic is not important, 
can you find the thread that went to sleep (should be pid 92279) and get 
stack trace for that?
