Re: Keyboard lockup with NetBSD5

Hello Frank,

something you did to this kernel made the bug nearly disappear :-)
I needed to type a lot and at very high speed to trigger this bug again.

Here is the kernel output:

IMHO the keyboard sends one "garbage" character (0x00), followed by a  
resync (0xf9) indicating a false character.
After that the keyboard repeats the last good character followed by a  
buffer full indication (0xfa).
The keyboard of the ECS machines should have a puffer of 10  
characters, but I don't know about the A1200.
Keeping in mind that Commodore had to make this machine cheap, maybe  
the onboard keyboard controller has a much smaller buffer?
But where does the 0x00 come from?
