Linux 2.4.28 breaks lm_sensors

Hi Marcelo, hi all,

We have been having reports that recent changes in the ACPI subsystem of
the Linux 2.4 kernel are breaking lm_sensors on a fairly large number of
systems. In particular, 2.4.28 is affected.

http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=1819
http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=1820

I did not report earlier because I thought the problem would be fixed by
the ACPI folks before 2.4.28 would be released. Unfortunately it wasn't.

The problem is already known, was reported for 2.6 kernels 4 months ago
and fixed there by David Shaohua. See this kernel bug report for the
detail of symptoms and the solution:
http://bugzilla.kernel.org/show_bug.cgi?id=3049

Applying the proposed patch to a 2.4.28 kernel make lm_sensors work
again on affected systems, while not causing trouble to unaffected ones
as far as I can tell.

Len, David, any reason not to apply the same fix to the 2.4 tree?

Thanks,
