Hey all, I know that AMD64's the preferred way to run >4 gig systems, but I'm having a weird situation with 6.2-RELEASE-p8 and 6-STABLE as of last night. When I compile the PAE kernel, my system performance drops like a rock. It still boots and everything still runs, but for instance, running the Flops port my megaflops drop from the 950 MFLOPS range to 4 MFLOPS. It feels about as fast as a 486. I'm not sure what I should try disabling. I tried nodevice usb, but that didn't seem to change anything. SMP and GENERIC kernels work fine. CPU: Intel Core Duo 2 Quad 2.4ghz Memory: 8 gig (4 2 gig dimms) Swap: 16 gig partition If I try to boot without ACPI disabled the kernel doesn't finish booting, it stops after ata7.
