Today I've csupped to latest RELENG_8 (hoping that maybe the problem was
fixed during last few months), rebuilt the kernel with USB_DEBUG option.
After fresh reboot, the following snippet releately pop up on the console
(hand-copied):
usb_needs_explore:
usb_bus_powerd: bus=0xc55cccf0 <-- bus= number changes
usb_bus_powerd: Recomputing power masks
uhub_explore: udev=0xc5647400 addr=1 <-- udev= number changes
uhub_read_port_status: port 1, wPortStatus=0x0100, wPortChange=0x0000,
err=USB_ERR_NORMAL_COMPLETION
uhub_read_port_status: port 2, wPortStatus=0x0100, wPortChange=0x0000,
err=USB_ERR_NORMAL_COMPLETION
(USB<->CRC32 has plugged in, no other USB devices)
Aroung zzz(8) time (keyboard die upon wake-up as described earlier with
100% CPU load -- fans are at full burst) debug mode yielded these:
uhub_child_pnpinfo_string: device not on bub
uhub_child_location_string: device not on bub
uhub_child_pnpinfo_string: device not on bub
usb_bus_powerd: bus=0xc55e2c78
usb_bus_powerd: Recomputing power masks
uhub_read_port_status: port 1, wPortStatus=0x0500, wPortChange=0x0000, err=USB
uhub_read_port_status: port 2, wPortStatus=0x0500, wPortChange=0x0000, err=USB
... up to port 8 ...
uhub_read_port_status: port 8, wPortStatus=0x0500, wPortChange=0x0000, err=USB
<< usual "(disconnected)" messages >>
usb_buf_port_set_device: bus 0xc55cccf0 devices[2] = 0

... usb_needs_explore: loop quoted above repeats; system unusable
Any ideas?
