I've been using 8-stable the last several weeks in preparation for the
new release and decided to give PAE a try for the first time. I rebuilt
my kernel with that option, and it booted fine. Then I rebuilt the
nvidia module and as soon as I kldload'ed it, boom!
panic: pmap_mapdev: Couldn't alloc kernel virtual memory
Unread portion of the kernel message buffer:
nvidia0: <GeForce 210> on vgapci0
vgapci0: child nvidia0 requested pci_enable_io
vgapci0: child nvidia0 requested pci_enable_io
panic: pmap_mapdev: Couldn't alloc kernel virtual memory
