Hi,
I'm seeing freezes with AMD64/CURRENT r227817 (as of Nov 22th). The
machine freezes hard when starting a virtual machine. It used work a few
weeks ago.
I've been using Bernhard's from a lot of time. 4.1.4 from a month ago
freezes. I had to apply the patch to fix the D_PSEUDO problem. I see it
was posted in the vbox mailing lists and commited upstream. So I
yesterday picked last virtualbox-port.tar.gz version at
http://svn.bluelife.at/nightlies. 4.1.6 included there also freezes the
machine.
So I recompiled the kernel with WITNESS, DEADLKRES and friends I see
a deadlock. This is the trace I got in my messages after rebooting the
machine:
Nov 25 08:57:06 portgus kernel: acquiring duplicate lock
of same type: "IPRT Fast Mutex Semaphore"

Semaphore @ \
/usr/ports/emulators/virtualbox-ose-kmod/work/VirtualBox-4.1.6_OSE/out/freebsd.amd64/release/bin/src/vboxdrv/r0drv/freebsd/semfastmutex-r0drv-freebsd.c:100
I don't know if I'll have time to check this. I will try the versions
in the ports tree (4.012?) but if it works it will allow us to work
until 4.1.X gets into the tree.
Any help will be appreciated.
