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" Nov 25 08:57:06 portgus kernel: acquiring duplicate lock of same type: "IPRT Fast Mutex Semaphore" Nov 25 08:57:06 portgus kernel: 1st IPRT Fast Mutex 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. Gustau
