Hi,
I've installed a PCI (not PCIE) video card in a FreeBSD 7-STABLE
(20080616 ~19:00 UTC) amd64 system, and when Xorg starts, the kernel
logs the message in the subject. Context:
Jun 17 11:27:30 bender kernel: drm0: <ATI Radeon RV280 9250> on vgapci0
Jun 17 11:27:30 bender kernel: info: [drm] Initialized radeon 1.25.0 20060524
Jun 17 11:27:33 bender kernel: info: [drm] Setting GART location based on new memory map
Jun 17 11:27:33 bender kernel: bus_dmamem_alloc failed to align memory properly.
Jun 17 11:27:33 bender kernel: info: [drm] Loading R200 Microcode

Is this anything to worry about? Part of the reason I ask is that the
machine locked up hard (had to cut power) the first time I hit
ctrl-alt-bs to kill Xorg, though I can't reproduce that reliably (or,
really, at all just yet). Let me know if I can provide more
information. full dmesg and pciconf output below.
Oh, kernel is GENERIC + "options DEVICE_POLLING".
thanks,
Jeff
