Comment(by pgf):

 i've reproduced, but it's not the bug i thought it was.

 while experiencing what was no doubt the Data Abort symptom over the
 weekend, i rebooted the machine with serial attached, and hit ESC for an
 ok prompt.  at that point i started getting the Keyboard Interrupt loop.
 since i had just been having trouble booting, and was now seeing a loop at
 the OFW commandline, i mistakenly thought i'd found the cause of the boot
 problem.

 this seems like a regression.  can you remind me of the use case for the
 new "USB serial access to OFW" feature?

 (the other symptom, Data Abort, is gone with q4d14jb.rom.)
