Package: linux-image-2.6-686
Version: 2.6.32+25
Severity: important
With Linux 2.6.32-trunk-686 & Linux 2.6.32-3-686, at least, on this Aspire One
Netbook, the system frequently boots into a state in which the keyboard does
not respond. The mouse (Synaptics touchpad) is still active, and as far as I can
tell everything else is working. My only recourse is to hit the reset button.
So this is nondeterministic, and so probably some sort of race? I *think* that
it happens more frequently if I happen to touch the ps/2 touchpad during boot,
but
it definitely does still happen when I keep my hands well away during boot.
Looking at /var/log/messages, this seem to be correlated with the
following message:
Apr 6 09:58:56 elf kernel: [ 4.789882]
atkbd.c: Spurious ACK on isa0060/serio0. Some program might be trying access
hardware directly.
So far as I can tell, this sort of message only appears when the kb is disabled.
Presumably, this interrupt is not really spurious, thus not serviced
and the kb controller waits forever for the keystoke to be handled?? Just
guessing :-(
Googling showed lots of rather confused discussion of this sort of message
from 3 years and more ago, but nothing that seemed relevant. Except maybe there
is
some unrecognised race lurking in there somewhere?
Boot parameters for this netbook are
elevator=noop enable_mtrr_cleanup.
And the netbook has a Super Talent SSD which is a bit faster & larger than the
one supplied by Acer.
The problem seems to happen more frequently with Linux 2.6.32-trunk-686
than with Linux 2.6.32-3-686. I have not collected any statistics, but my guess
is
something like 40% and 30% off boots, respectively. So pretty intrusive.

I guess it would be useful to have a copy of /var/log/messages as well, but as
it is
large I will wait until I have a response in case this is something
trivial/silly.
