next in thread | raw e-mail | index | archive | help
I recently updated my workstation at home to -CURRENT, and then noticed
(thanks to some discussion on ##freebsd) that VirtualBox had made it
into the ports tree. I installed it via ports, but upon trying to boot
a VDI image created under Linux (where it works just fine), I ran into a
kernel panic. When starting the VM, VirtualBox informs me of the key
combination to grab/release the mouse and keyboard. I click "OK" and
then the entire machine locks up.
The VM is Windows XP. 256 megs of RAM, 1 processor, VT-x/AMD-V is
enabled, with Nesting Paging disabled. The only option I changed was
the memory. All the others were the defaults.
I reproduced the panic quite easily by rebooting into single user mode,
fsck'ing the filesystems manually, booting into X, and then starting up
VirtualBox. Same thing happened when I launched the VM.
The panic:
This GDB was configured as
"i386-marcel-freebsd"...
Unread portion of the kernel message buffer:
panic: blockable sleep lock (sleep mutex) 32 @

Is there anything else I can do to help track this down?
