The basic idea behind my long complain (part 1 of original email) is simple.
Is it possible ACPI automaticaly disables a part of it's functionality if at
boot time it finds in bios an old and "ugly" ACPI v1.02 (1.0b) ? Here I
mean only the IMPORTANT part of acpi functions such as reboot and poweroff?
I would understand issues with some acpi features not working on my old PC
but reboot and poweroff should be rock!
There is no logical excuse why new 2.6 kernel cann't reboot PC that was just
fine with 2.4
and that "foolish" idea frustrated many not only me.
As of part 2 of email. Henrique, thank you for an idea to play with boot
options. Unfortunately acpi module and
kernel-parameters.txt<http://repo.or.cz/w/linux-2.6.git/blob/22763c5cf3690a681551162c15d34d935308c8d7:/Documentation/kernel-parameters.txt>specifically
are hard to see whole logical hearahi and navigate thru options
list. The only path left "keep-trying-all". As as an example I found
"boot=bios" works in my case, even it is not even mentioned in that doc.
Thanks to google ;)

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
