The patch in comment #29 was applied to linux-2.6.23-rc8. While executing the
'time cat /proc/acpi/thermal_zone/THRM/temperature' 1000 times, the following
messages repeat:

[  311.373860] ACPI: EC: lost interrupt
[  311.379419] ACPI: EC: increment interrupt counter
[  311.880903] ACPI: EC: lost interrupt
[  311.881790] ACPI: EC: increment interrupt counter
[  312.381975] ACPI: EC: lost interrupt
[  312.382875] ACPI: EC: increment interrupt counter
[  312.882075] ACPI: EC: lost interrupt
...and so on.

The the statistics of reading out the temperature sensor is slow:
min: 0.19s
avg: 1.707s
max: 11.009s
