Comment 2 Zhang Rui 2010-11-05 02:58:34 UTC
is this a regression?
if yes, what's the latest kernel that this bug doesn't exist?

please attach the acpidump of this box.

Comment 6 Zhang Rui 2010-11-08 00:26:31 UTC
we can not say it's a 2.6.37-rc1 regression for now as the problem happens after running for nearly 5 hours in 2.6.37-rc1.

Cristian,
it would be great if we can find out how to trigger this bug in 2.6.37-rc1.
e.g. please run "grep . /sys/class/thermal/*/*" after boot in 2.6.37-rc1, and attach the result and the dmesg output.

Comment 9 Zhang Rui 2010-11-08 01:20:42 UTC
it's not reproduced.
so let's say this is an intermittent EC failure.
Cristian,
how often did you see this bug? have you every tried to reproduce it successfully?
Comment 10 Len Brown 2010-11-09 02:23:05 UTC
Can you reproduce the error message more frequently
if you actively poll the temperature attributes?

eg.

while /bin/true; do
cat /sys/class/thermal/thermal_zone0/temp
cat /sys/class/thermal/thermal_zone1/temp
done

Not reproduce with successfully =(
Comment 13 Zhang Rui 2011-03-21 07:51:05 UTC
well, I don't know how to debug it if it can not be reproduced.
how many times did you see the bug?
could you please try the latest upstream kernel and re-open the bug once you see the problem again?
