Unfortunately it is still busted and I can't seem to figure out why. There are actually three problems that have it broken. The first is that at roughly the same time frame the driver started getting packets ( < 1500 bytes) that were spread over a huge number of mbufs ( > 16 and sometimes > 32 !) I have a fix for that in the new driver code. The second and worst is that the PMW kit ceases to call TransmitFrameCompleted. This causes the driver/card to run out of transmit buffers and there is no way to recover except reboot. The third problem (one I just ran into myself) is that since newbus the PCI bus gets probed before the ISA bus and this appears to cause the PCI probe to fail. I can't help but think that since newbus went in on 4/16 that there is some correlation with the second problem. I know the third problem is directly related to newbus, but it is a problem with the probe code in my driver. The first problem was me being naive and most likely is either some new big inefficency or some new big performance improvement, I am not sure which :) Needless to say I am very frustrated that I haven't been able to fix these problems, but I am still working on them. I still have a lot of cleaning up to do in the driver but these 3 things have me tied up. Any help would be greatly appreciated. I am getting ready to look for help on -hackers shortly.
