when the acpi thermal driver reads a bogus temperature, I find this in the
dmesg you attached:
[ 3217.967136] **** Context Switch from TID ffff88007cafe580 to TID ffff
[ 3217.967138] **** Context Switch from TID ffff88007cafe580 to TID
ffff88002f292540 ****

and it suggests there is a racing condition that we didn't care about before.
The patch in comment #55 should fix this problem.
If the patch in comment #55 doesn't help for this bug report, at least we can
see what's the difference between reading a good temperature and a bad one.
