I eliminated cards, and here is what /proc/interrupts reads:
CPU0
0: 2181209 XT-PIC timer
1: 351 XT-PIC i8042
2: 0 XT-PIC cascade
7: 0 XT-PIC parport0
9: 0 XT-PIC acpi
10: 700000 XT-PIC ohci_hcd
11: 380 XT-PIC eth0
12: 12849 XT-PIC i8042
14: 8027 XT-PIC ide0
15: 24 XT-PIC ide1
NMI: 0
ERR: 0
This is what /proc/interrupts read after the IRQ crash.
With this configuration this is what occurred:
hub 1-0:1.0: resubmit --> -108
hub 1-0:1.0: hub_port_status failed (err = -108)
irq 10: nobody cared!

I'll have another card to test in another day or so.
