Re: Blacklisted system / blacklisting bad

Dear Len,
using 2.6.18-rc7 on this box works like charm - using acpi=force. The bad
thing about it stems from the additional fact, that acpi has been disabled for
elder bioses by a switch checking for the bios age. I did not know about this
because 2.6.11 doesn't use the age checking.
However things may be, I tested according to your suggestion and things simply
work as expected.
You can argue that the compile time option for the age check is optional - but
i. e. SuSE is using it, at last.
So you may remove the blacklisting entry, but things will not change for the
user as the age checking forces me to use acpi=force anyway.
IMHO a "normal" user would have failed with this, both kinds of blacklisting
are bad (sure, for this specific system).
Is there any option to white-list systems in order to avoid the acpi=force
commandline switch? IMHO it will be hard for a "normal" user to cope with
this and to understand the relation between an "acpi=force" - switch on the
boot-commandline and a disfunctional USB interface. Just my two cent here ...

Anyway, patch for 2.6.18 is attached, thanks for your efforts,
take care
