I just installed FreeBSD 4.3 on a machine that runs Linux, and had been running FreeBSD 3.5-4.1, various releases. No problems, at least nothing major. However, when booting up after the install, the machine crashed before it set all devices. I noticed that the system had trouble with some of the USB devices, but didn't really think much of it. It just was taking it a long time to query the USB chain. That chain consists of two devices in their own port, and a joystick and Visor docking station plugged into a hub. The hub is a cheap Belkin unit like you find in CompUSA or Best Buy. For the second boot I unplugged the USB hub. This time everything was fine... I'm sending this mail from the FreeBSD machine's console. I can understand USB problems, and I have heard bad things about a lot of USB hubs. However, I don't generally expect a BSD kernel to die because of something like that, so I wonder if I've not found a bug. It seems to boot up fine without the hub so far, so this seems repeatable. If it fails to boot any time without the hub, I'll make sure to note that, but I really think there is something wrong in the USB code. When I can get back on the net I'll search some more, but right now I can't find any other similar reports. Anyway, here's the kernel crash dump that came up: Fatal trap12: page fault in kernel mode fault virtual address = 0x34 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01b35f6 stack pointer = 0x10:0xc046ead4 frame pointer = 0x10:0xc046ead4 code segment = base 0x0, limit 0xffffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (swapper) interrupt mask = net tty bio cam trap number = 12 panic: page fault -- shannon@widomaker.com _________________________________________________ ______________________/ armchairrocketscientistgraffitiexenstentialist "And in billows of might swell the Saxons before her,-- Unite, oh unite!
