Hi Nathalie, Thanks for your answer and pointer. Unfortunately it doesn't help. The patch you mention won't apply on my kernel alone, I need first to apply the patch from http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=c434b7a6aedfe428ad17cd61b21b125a7b7a29ce , then your patch applies OK. Unfortunately, it doesn't solve my issue. Booting this kernel still results in an interrupt issue with uhci_hcd. After boot, "cat /proc/interrupts" shows: CPU0 0: 188066 IO-APIC-edge timer 1: 308 IO-APIC-edge i8042 2: 0 XT-PIC cascade 4: 413 IO-APIC-edge serial 7: 3 IO-APIC-edge parport0 14: 1177 IO-APIC-edge ide4 15: 1186 IO-APIC-edge ide5 18: 1028 IO-APIC-level eth0, eth1 19: 8513 IO-APIC-level ide0, ide1, ide2, ide3, ehci_hcd:usb4 21: 100000 IO-APIC-level uhci_hcd:usb1, uhci_hcd:usb2, uhci_hcd:usb3 22: 0 IO-APIC-level VIA8233 NMI: 0 LOC: 187967 ERR: 0 MIS: 0 (The problem is with IRQ 21 for uhci_hcd) (It is to note that without those patches, I didn't see any IRQ managed by "XT-PIC", all were managed by the IO-APIC...)
