Hi

Thanx for the updated patch. Some feedback ...

I tested it with Xenomai 2.4.7 under Ubuntu 8.04.2  on three different
platforms
(AMD Athlon Desktop, Intel Core 2 Desktop, Intel Core Duo Laptop)

Typical system lockups when in the gnome desktop do NOT occur anymore !
Great :)

Initial observations when compared to Xenomai 2.4.5 with
adeos-ipipe-2.6.24-x86-2.0-07.patch.  :

1. Latency test shows a slight increase of about 5 to 10 % on the Intel
platforms.
(Still need to do the comparison on the AMD platform). This translates to
less than 5 uS
so it's ok for our case.

2. On the Intel Core 2 Desktop, our application has a much more significant
max scheduling jitter
of about 125 uS (compared with < 60uS for Xenomia 2.4.5). This 'increased
jitter' does not
show up on the other two platforms. Still trying to trace this one.
Already played around with
different ACPI and SMI settings, but no joy (:


Keep well
Vicki
