Robert,
First, thanks for all your dedicated work so far on the Xorg ports.
I realize this upgrade has been somewhat fraught with unexpected issues.
FWIW, things are not greener on the Linux side of the fence; many Ubuntu
and Debian users have reported issues with the newer Xorg and in
particular hald.

I still see the USB symptoms with xorg-server port as of today -- forced
rebuild with libpciaccess also. So amd64 is still regressed -- USB is
totally unusable there after X is started. My theory was that somehow
Xorg was stomping on the USB controller registers on this machine. The
USB controller on this box is ALi, card=0x81561043.
Is your usb sharing interrupts with the video card?
Yes, it appears so. This is an ASUS Vintage AH-1, uniprocessor amd64 box
w/ioapic enabled
from devinfo -r (abbreviated):
ohci0 17
ohci1 18
ohci2 19
ehci0 23
lspci -v jibes with devinfo -r -- the primary head got IRQ 18, the
secondary IRQ 255.
It appears msk0 is also sharing IRQ 18, though I haven't seen any
problems with networking; mskc0, however, is then configured to use MSI
(pseudo IRQ 256, 258), it is a PCI-e device.
When the system starts, the drm module has not been loaded, so the
Radeon (Sapphire X550) card hasn't been allocated its IRQ by FreeBSD.
After X starts, glxinfo and glxgers work fine. kldstat reports drm.ko
and radeon.ko got loaded by X as I would expect. I still see no IRQ
allocated for the radeon, either in dmesg output or in devinfo -r,
however, vmstat -i does show drm0 as sharing IRQ 18.
At this point, I rebooted and tried manually resetting the BIOS ESCD
table, unfortunately the BIOS on this machine won't let me tie IRQs down
to particular devices.
Does the issue occur if you aren't using a usb mouse?
I see the USB problems regardless of the kind of USB devices plugged in,
I continue to use a PS/2 mouse on the desktop as a workaround.
I see the bump on devel/libpciaccess re typo of rombase, and forced a
rebuild of xorg-server against the patched libpciaccess library
(probably not needed, as the .so ABI didn't change).
The USB problem is still present, unfortunately.
thanks,
BMS
