"Spurious NAK on isa0060/serio0" messages

[Adam Funk]

My computer was slightly damaged a few days ago by a power spike after
a power cut.  A local computer store diagnosed & replaced a failed
capacitor.  I hooked everything back up, including my PS/2 & VGA KVM
switch, and now I'm seeing this kernel message in the syslog

atkbd serio0: Spurious NAK on isa0060/serio0. Some program might be trying access hardware directly.

at varying intervals but fairly consistently 3 times per minute,
whether I'm logged in or not.  AFAICT everything works normally.

Do I need to fix anything, or should I just put it in the logcheck
"ignore" file?

Thanks,
Adam
