===========
----------------------------------------
Bug #3253: HAMMER2 on NFS server. "(nlock & MTX_MASK) != MTX_MASK"
http://bugs.dragonflybsd.org/issues/3253#change-13931
* Author: yellowrabbit2010

----------------------------------------
Hello,
the client machine writes (not very fast, like 150Kb/s) data to the
DragonFlyBSD NFS server with hammer2 partition.
The server dies periodically (3-4 days). These crashes do not depend on the
time of continuous work (I tried to reboot several times a day), but rather
just a coincidence of some circumstances.
I am using the master branch, radeon graphics driver with hardware acceleration
is disabled. Crashes occur both when idle at night and when working during the
day.
Here are the last three files, they refer to different commits on the master,
of course, but the error is the same.
I have all the vmcore.? and kern.? files and I can put them wherever you
specify.
