PS: Hm? What does "irq:0 18 ( 2) "ohci_hcd:usb4" "ohci_hcd:usb6" "radeon@pci:0000:01:05.0"" mean? Is the graphics sharing the IRQ with USB? spinymouse-sudo@64studio:~$ hwinfo | grep irq <6>[ 1.965458] atiixp 0000:00:14.1: not 100% native mode: will probe irqs later <6>[ 2.845182] ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 <6>[ 12.278057] parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE,EPP] irq = 22 irq = 21 irq = 25 irq = 18 irq = 0 irq = 0 irq = 0 irq = 0 irq = 0 irq = 0 irq = 16 irq = 0 irq = 19 irq = 18 irq = 17 irq = 18 irq = 17 irq = 16 irq = 22 irq = 24 irq = 0 irq = 0 class 0c, sub_class 00 prog_if 10, hdr 0, flags <>, irq 22 class 04, sub_class 01 prog_if 00, hdr 0, flags <>, irq 21 class 02, sub_class 00 prog_if 00, hdr 0, flags <>, irq 25 class 03, sub_class 00 prog_if 00, hdr 0, flags <>, irq 18 class 06, sub_class 00 prog_if 00, hdr 0, flags <>, irq 0 class 06, sub_class 00 prog_if 00, hdr 0, flags <>, irq 0 class 06, sub_class 00 prog_if 00, hdr 0, flags <>, irq 0 class 06, sub_class 00 prog_if 00, hdr 0, flags <>, irq 0 class 06, sub_class 04 prog_if 01, hdr 1, flags <>, irq 0 class 06, sub_class 01 prog_if 00, hdr 0, flags <>, irq 0 class 01, sub_class 01 prog_if 8a, hdr 0, flags <>, irq 16 class 0c, sub_class 05 prog_if 00, hdr 0, flags <>, irq 0 class 0c, sub_class 03 prog_if 20, hdr 0, flags <>, irq 19 class 0c, sub_class 03 prog_if 10, hdr 0, flags <>, irq 18 class 0c, sub_class 03 prog_if 10, hdr 0, flags <>, irq 17 class 0c, sub_class 03 prog_if 10, hdr 0, flags <>, irq 18 class 0c, sub_class 03 prog_if 10, hdr 0, flags <>, irq 17 class 0c, sub_class 03 prog_if 10, hdr 0, flags <>, irq 16 class 01, sub_class 06 prog_if 01, hdr 0, flags <>, irq 22 class 06, sub_class 04 prog_if 00, hdr 1, flags <>, irq 24 class 06, sub_class 04 prog_if 00, hdr 1, flags <>, irq 0 class 06, sub_class 00 prog_if 00, hdr 0, flags <>, irq 0 irq:1 0 ( 185) "timer" irq:0 1 ( 30657) "i8042" irq:1 4 ( 7) "serial" irq:1 7 ( 0) "parport0" irq:0 8 ( 1) "rtc0" irq:0 9 ( 0) "acpi" irq:0 12 ( 2017162) "i8042" irq:1 14 ( 59788) "ide0" irq:0 16 ( 1) "ohci_hcd:usb1" irq:0 17 ( 91) "ohci_hcd:usb2" "ohci_hcd:usb5" irq:0 18 ( 2) "ohci_hcd:usb4" "ohci_hcd:usb6" "radeon@pci:0000:01:05.0" irq:0 19 ( 2) "ehci_hcd:usb3" irq:0 21 ( 0) "ICE1712" irq:0 22 ( 137046) "ahci" "firewire_ohci" irq:0 25 ( 123575) "eth0" used irqs: 0,1,4,7,8,9,12,14,16,17,18,19,21,22,24,25 spinymouse-sudo@64studio:~$
