Which kernel version? Which version of "sensors" and libsensors
("sensors -v" will tell you)?
The non-linear numbering of the cores might be the cause.

Hi Jean,
sorry for the missing information.
$ sensors -v
sensors version 3.3.4 with libsensors version 3.3.4
$ uname -a
Linux inwest 3.10.25-1-lts #1 SMP Sat Dec 21 13:31:14 CET 2013 x86_64 GNU/Linux
Best regards,
Andreas

This is Core 18, alarm flag is missing.
This matches the output of sensors, but raises two questions:
1* Why are the alarm flags missing for 5 inputs?
2* getdents says 59 entries, but the above are only 27. Even adding 2
for . and .. and 8 for the label files, we're only at 37. So there must
be more files to read than libsensors is actually reading - presumably
your two missing cores are there.
So please provide the output of:
$ ls -l /sys/devices/platform/coretemp.0
I suspect this constant in libsensors is causing the problem:
#define MAX_SENSORS_PER_TYPE 24
The library assumes linear numbering, so anything beyond temp23 would
be ignored, which I suspect is the problem here.
This however doesn't explain the missing alarm files. I'm curious if
the "ls" command above will show them.
I would also like to see the output of:
$ grep '^\(processor\|core id\)' /proc/cpuinfo

Name too long. Jean, any idea how we can fix this ?

We have a first bug here, apparently some buffer isn't large enough so
the dynamic attribute name doesn't fit. The (trivial) fix is in the
coretemp kernel driver, I'll send a patch in a minute.

Here's the second issue, these indexes are too high for libsensors,
which stops at temp23. We can raise the limit to cover this case (and
I'll probably do that as an immediate fix) but in the long run it would
be great to have it computed dynamically at run-time so that the
problem doesn't ever happen again.
Fixes are coming, stay tuned.
