--vGgW1X5XWziG23Ko Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable [Based on a thread in -stable] I am trying to upgrade a Dell GX620 from FreeBSD 7.1 to a recent FreeBSD 8-stable and have run into a regression in the ukbd probe order. This box has no PS/2 ports and therefore I use a USB keyboard (and have removed atkbdc, atkbd and kbdmux from my kernel). All relevant USB devices are compiled in. In 7.x, ukbd probes before the kernel mounts root. In 8.x, ukbd probes after the kernel mounts root (it actually probes asynchronously after the "Enter full pathname of shell..." prompt). (This bit me badly because I managed to screw up my root disk name and got prompted with 'mountroot>' but had no keyboard). The GX620 is a P4 system with an ICH7 chipse. The keyboard is a Dell SK-8115 connected directly to a motherboard port (I've tried several different USB ports without improvement). I've also tried a Dell SK-8135 (which is the "multimedia" variant and has a builtin hub) which behaves the same. I've uploaded full details as follows: FreeBSD 7.x verbose dmesg: http://pastebin.ca/1776339 FreeBSD 8.x verbose dmesg: http://pastebin.ca/1776359 "pciconf -lv" (same in 7 & 8): http://pastebin.ca/1776363 The output from 'usbdevs -v' on FreeBSD 7 is: Controller /dev/usb0: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x= 0000), rev 1.00 --=20 Peter Jeremy port 1 powered port 2 powered Controller /dev/usb1: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x= 0000), rev 1.00 port 1 powered port 2 powered Controller /dev/usb2: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x= 0000), rev 1.00 port 1 powered port 2 addr 2: low speed, power 70 mA, config 1, Dell USB Keyboard(0x2003)= , Dell(0x413c), rev 2.00 Controller /dev/usb3: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x= 0000), rev 1.00 port 1 powered port 2 powered Controller /dev/usb4: addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), Intel(0x= 0000), rev 1.00 port 1 powered port 2 powered port 3 powered port 4 powered port 5 powered port 6 powered port 7 powered port 8 powered And the output from "usbconfig list" on FreeBSD 8 is: ugen0.1: <UHCI root HUB Intel> at usbus0, cfg=3D0 md=3DHOST spd=3DFULL (12M= bps) pwr=3DON ugen1.1: <UHCI root HUB Intel> at usbus1, cfg=3D0 md=3DHOST spd=3DFULL (12M= bps) pwr=3DON ugen2.1: <UHCI root HUB Intel> at usbus2, cfg=3D0 md=3DHOST spd=3DFULL (12M= bps) pwr=3DON ugen3.1: <UHCI root HUB Intel> at usbus3, cfg=3D0 md=3DHOST spd=3DFULL (12M= bps) pwr=3DON ugen4.1: <EHCI root HUB Intel> at usbus4, cfg=3D0 md=3DHOST spd=3DHIGH (480= Mbps) pwr=3DON ugen2.2: <Dell USB Keyboard Dell> at usbus2, cfg=3D0 md=3DHOST spd=3DLOW (1= =2E5Mbps) pwr=3DON The alternate keyboard shows up as: port 2 addr 2: full speed, power 100 mA, config 1, Dell USB Keyboard Hub(0= x1003), Dell(0x413c), rev 2.00 port 1 addr 3: full speed, power 50 mA, config 1, Dell USB Keyboard(0x201= 0), Dell(0x413c), rev 2.00 port 2 addr 4: low speed, power 100 mA, config 1, product 0x3010(0x3010),= vendor 0x413c(0x413c), rev 2.30 port 3 powered --=20 Peter Jeremy --vGgW1X5XWziG23Ko Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (FreeBSD) iEYEARECAAYFAktpRkwACgkQ/opHv/APuIfwoACgqeezejIlL49fMeui60X2ZVOZ ZNkAnRrU6VL75MAYxV7AqzAHG5DiohLI =OVLv -----END PGP SIGNATURE----- --vGgW1X5XWziG23Ko--
