Comment (by archaic at linuxfromscratch.org):

 The bugreports are indeed what you had asked for. There was very little
 change in all of the different combinations you asked for. Anyway, with
 the new loop instructions things became much better. After 7 boots without
 a usb device plugged in (but with usbcore and hid still loading) there
 were no failures. Once I plugged in my mouse I got  5 boots without and 4
 boots with the error. Everytime there was an error, it appears the problem
 was with the kernel assigning a location for the device. Here's the
 output:


 {{{

 uhci_hcd 0000:00:10.2: new USB bus registered, assigned bus number 3

 }}}

 After this, the kernel reassigns usb 1-2 to another address successfully.
 Again, it seems this delay is prompting the bugreport because on the boots
 which assign the device correctly the 1st time, there is no bugreport.
 Also, the bugreport is now reduced to just usb stuff, but I am attaching
 it in case you want to see it.
