| |
2.6.0 works fine on this hardware, including the twitchy built-in USB controllers.
Loading the uhci-hcd module on 2.6.1 gives me the following:
drivers/usb/core/usb.c: registered new driver usbfs drivers/usb/core/usb.c: registered new driver hub drivers/usb/host/uhci-hcd.c: USB Universal Host Controller Interface driver v2.1 uhci_hcd 0000:00:07.2: UHCI Host Controller uhci_hcd 0000:00:07.2: irq 225, io base 00009400 uhci_hcd 0000:00:07.2: new USB bus registered, assigned bus number 1 hub 1-0:1.0: USB hub found hub 1-0:1.0: 2 ports detected uhci_hcd 0000:00:07.3: UHCI Host Controller uhci_hcd 0000:00:07.3: irq 225, io base 00009800 uhci_hcd 0000:00:07.3: new USB bus registered, assigned bus number 2 hub 2-0:1.0: USB hub found hub 2-0:1.0: 2 ports detected hub 1-0:1.0: new USB device on port 1, assigned address 2 APIC error on CPU1: 00(40) APIC error on CPU1: 40(40) APIC error on CPU1: 40(40) APIC error on CPU1: 40(40) APIC error on CPU1: 40(40) APIC error on CPU1: 40(40) APIC error on CPU1: 40(40) APIC error on CPU0: 00(40) APIC error on CPU1: 40(40) APIC error on CPU1: 40(40) APIC error on CPU1: 40(40) APIC error on CPU1: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU1: 40(40) APIC error on CPU1: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU1: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU0: 40(40) APIC error on CPU1: 40(40) irq 177: nobody cared!

And so on, until I shut down the system.
The 20031203 ACPI patch fixes the problem.
