My hardware is:
Commodore Amiga 1200 rev 1D
Blizzard 1260, 68060 <at> 50 MHz
SCSI Kit IV (no drives or cables currently attached), 64 MB RAM (1 SIMM)
storage: alternating between a 2 GB CompactFlash card and a 1 GB 3.5 Maxtor IDE drive
PSU is a 50 W switchmode supply, good for 5 A <at> 5 V
I've been trying out a few recent kernels, and GENERIC 4.0 and 4.0.1 do not appear to exhibit the problem, but
GENERIC 5.0 and 5.0.1 do, as does Frank's amiga_timecounter_fix 5.0.1 test kernel. The keyboard
weirdness under 5.x occurs regardless of whether booting off the CompactFlash or the IDE HDD. I'm quite
prepared to accept it's just my hardware, but it works fine under AmigaDOS and seemingly all NetBSD but
BTW, I couldn't easily compare interrupt rate figures across all these kernel versions as the systat
binary only seems to work with the kernel it was compiled for.

That sounds great - I'm glad I'm not the only one who likes custom rack gear. :) I nearly bought an A2000
motherboard recently and would probably have put it in a rack enclosure.
