So, can someone give an estimation as to how soon that may be and how soon it may make it to 8-stable? If it's going to be a while I may look into adding a card using a different driver to test. > igb(4) in HEAD would be more stable but I haven't had time to experiment it. Last time I tried previous igb(4) driver which was shipped with 8.0-RELEASE showed several issues under high network loads as you might know. I have a patch which could be applied to 8.0-RELEASE or stable/8. http://people.freebsd.org/~yongari/igb/igb.buf.patch6 The patch would fix unresponsive system under high network load as well as reducing number of interrupts. The patch also contains bus_dma(9) and watchdog timeout fix. > My network device is: > > igb0@pci0:8:0:0: class=0x020000 card=0x10a715d9 chip=0x10a78086 rev=0x02 hdr=0x00 > vendor = 'Intel Corporation' > device = '82575EB Gigabit Network Connection' > class = network > subclass = ethernet > > > Thanks, > Alan
