I don't even know whom to refer you to. Maybe ask in LKML directly?
Use the subject "libata EH running when switching VTs". If one of
those VTs are in X.org control, say that as well.
I'm wondering why I get this in /var/log/messages w/ kernel 2.6.37 when I
switch from VT7 (running xorg ) to VT12 (or 1 or 2 or another number) and
back:

I'm running an almost stable Gentoo on a ThinkPad T400 with current

Is that the only output you're getting? Can you post the full dmesg log
from bootup?
Of course - attached here
Curious, there seems to be no indication of why EH was triggered,
doesn't seem to be have been due to an error. Does this also happen in
single-user mode or with minimal processes running? It's possible that
userspace is triggering this somehow.
