In the SyncLink drivers I've always passed a devname that is unique to each device instance, using the form printf(devname, "%s%d", basename, instance_num). Ethernet device instances also seem to do this. I see that the generic serial 8250 driver uses a constant name, as does aic7xxx. Unique device names are useful for identifying which device instance is on a particular interrupt (/proc/interrupts), but other drivers beside uhci_hcd use a constant name so I guess that is legal :-) Either way, the generic IRQ code should deal with duplicates without generating an oops. -- Paul Fulghum [EMAIL PROTECTED] ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
