This state seems the hardware problem. Probably TX pending was not processed, so any pending interrupts is nothing. What CardBus bridge are you using? If TI12xx bridge, can you try the attached patch? (Try "disable_clkrun" module option with yenta_socket.ko) -- OGAWA Hirofumi [PATCH] pcmcia: Add disable_clkrun option I received report that transmission of Realtek 8139 doesn't work. The cause of this problem was CLKRUN protocols of laptop's TI 12xx CardBus bridge. And I remember that this problem had happened on Thinkpad before. In the case, problem seems solved by similar workaround of sound/oss/cs46xx.c. This patch adds "disable_clkrun" option as workaround of problem to yenta_socket. Please apply.
