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 : http://cipsa.physik.uni-freiburg.de/~zwerger/Vaio/Intel_Mobile_Temp-Prob.pdf Here is the fix on fuckin' Windows 98 (as a curiosity) : http://cipsa.physik.uni-freiburg.de/~zwerger/Vaio/indexeng.htm
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 ! Florent CHANTRET
