The only difference that this workstation has from the one I use at work regarding interrupts is that here (where the silo overflows occur) irq9 is shared among ohci2 and acpi0. 20 ?? WL 0:00.00 [irq9: ohci2 acpi0] I vaguely remember having problems with silo overflows again in the past; when irq9 was shared. Now I have to find out how to assign another irq to ohci2. Thanks Roman :-)
