Hi all, I have an hp dv9000 laptop (amd turion) nvidia graphics engine. I boot with kernel options noapic nolapic acpi_use_timer_override I also have ndiswrapper 1.48 For the most part its stable but there are times when the machine just locks up. I am running centos 5 x86_64 with all the updates. Anyone have a similiar machine and possible more stable OR know of another kernel boot option to make things more stable? Thanks, Jerry
