Sorry John, I didn't realise that Windows was running OK... (I presume it runs OK at full CPU load.) Have you tried running a different distro (say Koppix from CD)? Is ACPI enabled? Try switching this setting on. What kernel are U using? I presume it is 2.4.x series :-) Is it stock or custom? You might try a custom kernel with ACPI statically linked and APM left out completely (APM can potentially clash - although I think this problem is fixed now in the 2.4.x kernel). Does <dmesg> have anything useful in it? Maybe you could post it here? Whats lurking in your /proc/ directories (interrupts, pci, etc.)? I am just clutching a straws here but it does sound like the Linux interrupt hander is shagged. So first place to check is ACPI settings I guess... Robert
