I'm running 7.0-RELEASE. The machine hangs when I use qemu, specifically with a linux VM, and more specifically after grub loads the kernel and it spits out the "Starting up ..." message. Then... nothing. Just before the crash, I see complaints about my sound hardware on the console; it doesn't seem related, but here it is: oss: Could not initialize DAC oss: Failed to open `/dev/dsp' oss: Reason: No such file or directory oss: Could not initialize DAC oss: Failed to open `/dev/dsp' oss: Reason: No such file or directory audio: Failed to create voice `pcspk' pcspk: Could not open voice I haven't touched /usr/include since I used freebsd-update to go from the last RC to RELEASE, and I'm using the -RELEASE GENERIC kernel, so I presume they're in sync. I am definitely loading the correct kqemu; I rebuilt it to check the md5sum against the one being loaded by kldload (in /boot/modules/). I suspect I might need to enable kernel debugging. I'll check the handbook and do that if necessary. If need be, what should I be looking for / post? Thanks a lot for your help.
