On my archlinux installation, randomly (it varies between 5 minutes and 5 hours), an interrupt is uncatched on bus IRQ18. When I type dmesg, I can read:
irq 18: nobody cared (try booting with the "irqpoll" option)
Booting with the irqpoll option doesn't change anything, unfortunately. In the file /proc/interrupts, the line corresponding to IRQ18 is :
18: 0 0 41 13812 IO-APIC-fasteoi pata_jmicron, ohci_hcd:usb6, ohci_hcd:usb7, ohci_hcd:usb8, ohci_hcd:usb9
When the interrupts happen, I have approximately 1 to 2 seconds of mouse and keyboard lag (system is really unusable ).
If anyone has an idea on how to fix this really annoying problem, let me know
Thanks a lot
ps : I also had this same problem on ubuntu on my machine.
