  * milestone:  Not Triaged => 4-firmware


Comment:

 Fixed in [http://tracker.coreboot.org/trac/openfirmware/changeset/3536 svn
 3536], which adds an interlock to skip the USB keyboard interrupt handler
 if the non-interrupt execution path is in the middle of a USB bulk or
 interrupt pipe method.

 Test builds:
  * [http://dev.laptop.org/~quozl/q7b14jc.rom q7b14jc.rom] for XO-4
 (testcase: attach USB keyboard directly, attach USB drive directly, see
 below),
  * [http://dev.laptop.org/~quozl/q3c10jb.rom q3c10jb.rom] for XO-1.5
 (testcase: attach USB keyboard via an external hub, attach USB drive
 directly, see below),

 Common testcase conclusion ... do repeated fs-update, it should complete
 without error and USB keyboard should be functional afterwards.
