Here is info from a computer where the keyboard works occasionally at
boot (about 50% of the time). Users reboot until the keyboard works.

Hmm, this is a USB keyboard so let's CC Jiri in addition to
linux-input...

Thanks for the report.

First question before we start any further analysis -- what is the latest 
known-good version of the kernel, where this problem didn't happen on this 
particular computer?

Thanks,
