Guenter,
We're evaluating the new card in a open chassis. It is on the test bench
with a table fan for cooling. I turned off the fan and got:
ENTER show_temp
cpu 0 (0)
status_reg @ 19C
eax = 885E0000 edx = 0
temp = 1770 valid = 1
EXIT show_temp
It seems like you've seen this before. What's going on?
Thanks,
Mike

Guenter,
Thanks for responding. The cards are both made by Emerson. The old
one is a COMX-430. The new one is a COMX-440.

Yes, Jean was right, same issue, same response.
One thing to try might be to see what happens
if you put the system under load, ie heat up the CPU.
Can you try that ?
Thanks,
Guenter

What Atom chip ? Can you provide output of /proc/cpuinfo ?
Thanks,

Do you have any additional information pertaining to ticket 2382?
The CPU card we use in our products is going end-of-life. The CPU
card vendor send us a new card that is supposed to be a drop in
replacement (it's the same card with a newer Atom chip). The new
card returns an error when reading the coretemp:
# cat /sys/bus/platform/devices/coretemp.0/temp2_input
cat: read error: Resource temporarily unavailable
#
Some printk debugging yields:
ENTER show_temp
status_reg @ 19C
eax = 8620000 edx = 0
temp = 0 valid = 0
EXIT show_temp
This looks like the same issue described in your ticket 2382.
Any information you can provide will be appreciated.
