Is this really correct? Do we alloc and not > free it in this case? Yes, it is true :-) We allocate all the interrupts needed for the entire system as we probe the busses and devices. But with MSI, the MSI vectors are allocated and liberated with pci_enable_msi()/pci_disable_msi() and related calls. I'll add the necessary ifdefs, thanks for the report. - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
