I looked at the issue some time ago but as I could never reproduce it, it never got fixed. Can you verify whether a subset of the interupts would also work? I would be particularily interested in the whether leaving the receive interrupt RINTM enabled would be OK. The receive interruupt would need to be in place if the driver gets PXE enabled. I will test it on the cards that I wrote it with and try to test it on a VMware nic. If there is no issue I will commit it to the cvs. Thanks again Tim |
