The problem seems to be that when VMware's guest is using the CPU the CPU stays at C2 and is not promoted to C1. This causes very high delays in some of the apps. I am running VMware 3.2 with kernel 2.4.19 and ACPI 20020821, I have been reluctant to try the newer ACPI drivers since I finally have things on my Presario 2710CA working quite well. When I do get some time I do intend to try the newer ACPI driver though. It has been a pain to go through each version and determine where I must hack to disable the CPU idle handler. I have also found that I must use a "corrected" DSDT since the one in the notebook is buggy. For what it is worth I too think this is an issue that VMware must correct. I have sent them emails regarding this issue but have never seen any response. I think more people have to complain about this problem before they will do anything to fix it. Feel free to email me if I can be of any assistance to you. Best Regards - Troy On Wed, 2002-11-20 at 18:16, Francis Yom wrote: > Hey guys, > > I'm having a problem with ACPI and VMWare.
