Hi,
I've sent a message to debian-kernel with no success, so I'm trying to
report a bug about this problem I've faced. In my Compaq Presario 2100,
when I boot the system with "acpi=on" as one of my kernel parameters,
the system hangs when trying to initialize ACPI (it has happened to all
2.6 versions I've tried). I've looked into the web to find out something
to fix this issue and I found a tiny patch that solved the problem. The
patch basically disables APIC timer before ACPI initialization and
re-enables it when ACPI initialization finishes. Below I write the patch
for your knowledgement.
Hope this helps solving the problem!
Thanks a lot,
Bruno.
