I was testing so hurd, that not only my problematic machine
with 4.6-STABLE, as described in kern/42260, crashed, but
my router running 4.6.2-RELEASE (27 August build, configuration
described in kern/42030) also crashed... :E
Once with acquire_lock() [1], once with xl_newbuf(). It's hurd for me
to reproduce it so I'm not opening the new problem. I provide this
here cause it's a curiosity. ;)
[1] Note, there were no special HDD activity. I was uploading files
over FTP to /dev/null on this machine...
please be patient while loaded modules are resolved
