I don't think I > tried 2.5.68. Should I and see if it was something in a patch to 2.5.69? Okay. I think I have figured some things out. With 2.5.69-bk4, I have ACPI and APM built into my kernel. If I boot normally, ACPI loads first and I get timeouts and my USB trackball doesn't register with input. If I boot with noacpi, I still have the same problem. If I boot with pci=noacpi, I do *not* have the problem. I still have the timeout, but my trackball works. However, I have many lines of an acpi_irq handler and call trace with the comment 'irq 20: nobody cared!'. I also get 'APIC error on CPU0: 00(40)' and 'APIC error on CPU0: 40(40)' a couple dozen times each. If I boot with noacpi *and* pci=noacpi, I have the all of the problems mentioned; no trackball and the pci=noacpi related problems. Someone mentioned using noapic, but it doesn't have any effect. Any questions?
