Fortunately this problem is now RESOLVED. Briefly, the root cause of it is * the wrong connection method between the KVM switch * and the PC motherboard * * # where KVM switch means hardware device that allows a * # user to control multiple computers from a single * # keyboard, video monitor and mouse. * # http://en.wikipedia.org/wiki/KVM_switch Only one (NOT two) of the two PS/2 connectors from the KVM switch was plugged into the PC motherboard, which is considered to be WRONG officially (by the KVM switch vendor). ------------------------------ The KVM switch I use is corega CG-PC2KVMCA, whose detail is as follows:: * KVM switch: corega CG-PC2KVMCA http://corega.jp/prod/pc2kvmca/ ---------- (1) It accepts the following as console: - PS/2 and USB keyboard - PS/2 and USB mouse - USB 2.0/1.1 hardware - Analog/RGB display monitor (2) The connection interfaces available to the PC are as follows:: - USB (for keyboard, mouse, and other hardware) - PS/2 (for keyboard and mouse) - Analog/RGB display monitor I connected the PS/2 keyboard and the PS/2 mouse to the above-mentioned KVM switch, which is not wrong. The PC motherboard that is connected to the above-mentioned KVM switch is GIGABYTE GA-P55A-UD5, whose detail is mentioned in the original message I posted:: * Motherboard: GIGABYTE GA-P55A-UD5 http://www.gigabyte.com/products/product-page.aspx?pid=3237 ---------- (1) BIOS ver = F12 (latest) (2) Chipset: Intel P55 Express (3) Only one PS/2 connector is available. (4) USB 3.0 ports are available as well as USB 2.0/1.1 ones. I connected the cables between the KVM switch and the PC motherboard. These cables provide the following connector at the side of the PC motherboard:: (a) USB (b-1) PS/2 keyboard (b-2) PS/2 mouse (c) Analog/RGB display monitor I plugged (a), (b-1), and (c) into the PC motherboard. The connector (b-2) was NOT plugged, because it is ONLY ONE PS/2 connector that is available at this PC motherboard. However, the KVM switch vendor informed me that this connection method was WRONG and that only the following two patterns are accepted as the PS/2 connection method:: (OK) BOTH OF (b-1) AND (b-2) are plugged into the PC (OK) NEITHER (b-1) NOR (b-2) are plugged into the PC ----- (NG) only (b-1) is plugged into the PC (NG) only (b-2) is plugged into the PC Now, only (a) and (c) are plugged into the PC motherboard. Under this circumstance, no trouble occur, independently of the following bios setting:: = "Enabled" / "Disabled" = "Enabled" / "Disabled" Finally, I would like to thank those who gave me the comments. -------------------- Original Message -------------------- Date: 16 Jan 2011 15:48:21 +0900 Message-ID: <20110116064821.12622.qmail@ts1.inter7.jp> To: freebsd-usb@freebsd.org From: Norihiko Murase Subject: FreeBSD hangs while booting with USB legacy support off List-Id: FreeBSD support for USB URL: http://lists.freebsd.org/pipermail/freebsd-usb/2011-January/009849.html Hi, My name is Norihiko Murase. I would like you to give me the comments/suggestions about the symptom described below. When I started the FreeBSD installation system via DVD (FreeBSD-***-RELEASE-i386-dvd1.iso), the system hangs while the devices are being probed. The last lines displayed was the following:: pci4: on pcib4 pci4: domain=0, physical bus=4 Curiously, the system does NOT hang at all if the bios setting of the box is changed as follows: = "Enabled" (from "Disabled") # opposite to PR#91906 ?! # http://www.freebsd.org/cgi/query-pr.cgi?pr=91906 After I change the bios setting as described above, the following lines are displayed:: pci4: on pcib4 pci4: domain=0, physical bus=4 found-> vendor=0x1033, dev=0x0194, revid=0x03 domain=0, bus=4, slot=0, func=0 class=0c-03-30, hdrtype=0x00, mfdev=0 cmdreg=0x0006, statreg=0x0010, cachelnsz=16 (dwords) lattimer=0x00 (0 ns), mingnt=0x00 (0 ns), maxlat=0x00 (0 ns) intpin=a, irq=12 powerspec 3 supports D0 D3 current D0 MSI supports 8 messages, 64 bit MSI-X supports 8 messages in map 0x10 map[10]: type Memory, range 64, base 0xfbcfe000, size 13, enabled pcib4: requested memory range 0xfbcfe000-0xfbcfffff: good pcib4: matched entry for 4.0.INTA pcib4: slot 0 INTA hardwired to IRQ 18 pci4: at device 0.0 (no driver attached) Detail of the environment under which I tried is as follows: * OS: FreeBSD 6.4-RELEASE 7.3-RELEASE 8.1-RELEASE * Motherboard: GIGABYTE GA-P55A-UD5 http://www.gigabyte.com/products/product-page.aspx?pid=3237 ---------- (1) BIOS ver = F12 (latest) (2) Chipset: Intel P55 Express (3) Only one PS/2 connector is available.
