Hi Mouse, Thank you for taking the time to answer me in such detail. I don't want you to think I haven't read your message. I have, and I'm still baffled. Not by what you said -- although I don't have a scope and you definitely understand this stuff at a level I don't -- but because like you I haven't been able to form a coherent theory.
The server still crashes intermittently, but mirabile dictu has been up for 4 days. Soekris shrugged, not something they've seen before. I found another power supply, albeit only 1100 mA, but haven't tried it.

After it's booted, at the login prompt, on the machine that usually (not always) doubles the letters, I see this on pasting: I paste: jklowden I type a space I paste: hello Total output: jklowdenjklowden àhelloxello Several pastings of "hello": helloxellohelloxellohelloxello Typing hello at different speeds: hxeelllloohxeelllloohxeelllloohxeelllloo This is *not* identical to the previous test; it was just easy to do. I'm on a different board, and I'm at the NetBSD login prompt. Sometimes changing multiple factors makes isolation easier.

Yes. ;-) I've always found breakout boxes too expensive to bother with; replacing the cable and/or trial-and-error always solved the problem cheaper. But this sure is one time I could use one.
