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...)
The errors I get in /var/log/messages are :

Disabling IRQ #21
At boot, IRQs seem to be distributed this way:
PCI: Probing PCI hardware
PCI: Probing PCI hardware (bus 00)
PCI: Using IRQ router default [1106/3189] at 0000:00:00.0
PCI->APIC IRQ transform: 0000:00:0a.0[A] -> IRQ 18
PCI->APIC IRQ transform: 0000:00:0b.0[A] -> IRQ 19
PCI->APIC IRQ transform: 0000:00:0f.0[A] -> IRQ 19
PCI->APIC IRQ transform: 0000:00:10.0[A] -> IRQ 21
PCI->APIC IRQ transform: 0000:00:10.1[B] -> IRQ 21
PCI->APIC IRQ transform: 0000:00:10.2[C] -> IRQ 21
PCI->APIC IRQ transform: 0000:00:10.3[D] -> IRQ 19
PCI->APIC IRQ transform: 0000:00:11.1[A] -> IRQ 22
PCI->APIC IRQ transform: 0000:00:11.5[C] -> IRQ 22
PCI->APIC IRQ transform: 0000:00:13.0[A] -> IRQ 18
PCI->APIC IRQ transform: 0000:01:00.0[A] -> IRQ 16

Hope this may help...
