I've ported the following version of the 8139 driver to another proprietary OS that runs on a Pentium PC (originally written by Intel): * $FreeBSD: src/sys/pci/if_rl.c,v 1.38.2.7 2001/07/19 18:33:07 wpaul Exp $ I can get it to run in polled mode but when I try to run in interrupt mode after about 15-20 transmit packets the transmit interrupt stops firing. After a while the receive interrupt stops firing also. I tried to add recovery when the transmit queue is full (I'm only using 4 packets at this point in time) but that doesn't help. I've checked the 8139 IMR and also checked the PC ports to make sure interrupts are being disabled. I also checked my Interrupt Descriptor Table to make sure the OS isn't clobbering it. Can you think of a reason why resetting and restarting the 8139 would not allow interrupts to start up again? Any ideas would be greatly appreciated. I've been struggling with this for several weeks now. I've attached my source code but I don't know if you'll be able to follow it. Mark Stolphome | help
