I'm not sure if that is what you expected but anyway here it is.

done.

Line 218 of "cpufunc.h" starts at address 0x2f6c <ehci_get_port_speed_hostc+44>
   and ends at 0x3fae <ehci_device_isoc_fs_enter+110>.


In the meantime I have 3 more panics from the original kind "panic: thread's
sleep queue 0 is not empty".
