SubjectSMBALERT# thermal sensor signal for Intel PII in the kernel ?
Hi geeks and guru's ;o)

Even if I'm a developper, I'm not there for the moment to help you
developping this wonderful Linux Kernel. Later, perhaps ;o)

But, I've a problem with my laptop Sony VAIO powered by a bugged as hell
Intel PII Celeron (lot of customers from Sony have the same problem and
there is no support from this fuckin' company, nor from Intel, and I don't
think contacting Micro$$$$oft is the good thing to do).

My laptop randomly shutdown due to a bug in the thermal sensor of the PII
sending a SMBALERT# signal. There is no solution for NT fuckin' OS (only a
trick on "WinDaube" 98 (french expression for WinShit ;o))

I don't want to be on an unstable fuckin' system, so I decided to
permanently switched to Linux (I was always reticent, I was considering
Linux was the best stuff for server but not so ready yet for desktop :
crappy fonts, some applications missing or not so user-friendly, but I'm
changing my mind), cause there is a real support, and tha ability to see the
source code. Open Source ruleeezzzzzzzzzz ;o)

But let's go to the problem :

Here is the Intel stuff about the bug :
Here is the fix on fuckin' Windows 98 (as a curiosity) :

So there is a software way to fix this hardware bug.

So I've build a 2.4.20 kernel without all the APM,ACPI, PM at boot, CPU
Idle and "Machine Check Exception" but I've still the problem. The kernel
still answer to an SMBALERT# which cause the machine to shutdown.

So, before asking in the ML, I've searched on Google and Google Groups
without success (there is quite nothing about SMBALERT#).

I've grepped all the 2.4.20 source code but there is anywhere the presence
of SMBALERT# in a comment. I've noticed some codes about SMBus (which I
think include the SMBALERT functionnality) but I don't know if I can
deactivate SMBus in the kernel config and if it is safe to do it.

There is several functions in the kernel for SMBus so if I must patch the
code to deactivate this precise signal, any help would be appreciated ;o)

If I can fix it, I will try to convert all the consumers of the F-serie VAIO
bugged to Linux ;o)

Thanks for your answer and sorry if this is not the good place to post but
I've searched a lot before. I don't want to erase Linux to put a "Windaube
98" help help help ;o)

Regards and respect for your great work !
