I've already posted this to FreeBSD-questions and gotten no response. I am hoping this is appropriate for the usb-bsd and -STABLE lists. Since that post, I have managed to get a kernel dump during boot, but I am not experienced at kernel debugging and do not know how to get boot messages from the core dump. If full boot messages are needed, please tell me how to get them and I will post them. I have compiled in the USB debugging options but the messages scroll by too fast to read at boot-time and there are no USB messages where the kernel hangs.I can also post my kernel config file if needed. Again, any help is appreciated. The problem: Whenever I boot a kernel with USB support compiled in, the machine hangs at boot, after having already successfully detected uhci0 and usb0. It hangs between the sio1 and at0 probes. When I do 'boot -v' I see that the machine hangs at the following message: isa_probe_children: probing PnP devices I am running 4.0 -STABLE on a Dell Inspiron 3200 laptop. I have an Intel 82371AB/EB (PIIX4) USB controller, and a TI PCI-1131 pccard controller. The BIOS's PnP OS option is disabled. I'm afraid I can't give full boot messages with the problem kernel, as it hangs during boot. I have set up my kernel conf file so that my pccard controller pcic0 uses IRQ 11 instead of the default 10, since my USB controller uses IRQ 10. This is what Win98 uses on this machine. Previously they both used IRQ 10. Behaviour was the same before that change (ie: pcmcia works, USB doesn't). Here are the USB lines from my kernel config: device uhci # UHCI PCI->USB interface device usb # USB Bus (required) device ugen # Generic If on the other hand I boot a kernel without USB support, and try to load USB support as a module with 'kldload usb', the machine scrolls the following message indefinitely and ceases to respond to anything short of CTRL-ALT-ESC or a power cycle: usb0: host controller halted. I can drop into DDB with CTRL-ALT-ESC for only a limited time in both the kernel and module cases. If I wait several seconds after the apparent hang or scrolling messages, the machine won't even drop into DDB. uname output: FreeBSD chiba.ether 4.0-STABLE FreeBSD 4.0-STABLE #25: Sat Jun 17 12:39:54 CDT 2000 root@chiba.ether:/usr/src/sys/compile/CHIBA i386 Any help is appreciated, Barry Kelly To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
