Hi, I currently am writing code for the FreeBSD SMP kernel that will allow us to use symmetric IO handling with all CPUs. This basically involves changing the kernel to use a device called the "IO APIC" in place of the 8259s. I now have code that does this, with all INT devices working properly EXCEPT for my ed NIC card. I have tried different slots and different cards, but I continue to get: [ date/time ] /kernel: ed0: device timeout I am occasionally loosing the INTs expected to be generated by ed_xmit(). The ed_watchdog() routine usually recovers gracefully (network actually locked twice since running this code: approx 2/3 weeks). Could someone explain why the ed0 cards might loose this INT? Any clues/insight appreciated! (please cc: me directly) -- Steve Passe | powered by smp@csn.net | FreeBSD
