Once drm is loaded and X opens it, the ddx driver should request that the irq handler be installed. At that point, dmesg should show something resembling the following. vgapci0: child drm0 requested pci_enable_busmaster info: [drm] AGP at 0xc0000000 256MB info: [drm] Initialized i915 1.6.0 20080730 drm0: [ITHREAD] I have code to enable msi for drm, which has been at least minimally tested on intel and ati. FWIW, linux does not support msi on radeon yet, so I got the jump on them there... The outstanding issue with that code is that I still need to implement a blacklist for certain devices that report msi capability, but don't (intel 945gm, is the only known chip atm). Does the issue still occur if drm is disabled? robert. > 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 > > _______________________________________________ > freebsd-stable@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org" -- Robert Noland <rnoland@FreeBSD.org> FreeBSD [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (FreeBSD) iEYEABECAAYFAkmQh0kACgkQM4TrQ4qfROO26QCfSCPARz0lb50RJHxAYgA0rTem 3igAnA1FqQSt7CQdNZ/jrekwa94BvMY1 =9cPB -----END PGP SIGNATURE-----
