No. The light (that is somewhere _inside_ the card for the R2BE-100) stays on. > What does mii-tool report? This is what mii-tool reports while the link is still up: |Basic registers of MII PHY #0: 1000 782d 0040 6331 00a1 45e1 0005 2001. | The autonegotiated capability is 00a0. |The autonegotiated media type is 100baseTx. | Basic mode control register 0x1000: Auto-negotiation enabled. | You have link beat, and everything is working OK. | Your link partner advertised 45e1: Flow-control 100baseTx-FD 100baseTx 10baseT-FD 10baseT, w/ 802.3X flow control. | End of basic transceiver informaion. Invoking mii-diag after provoking the network freeze freezes the entire machine. Not even magic sqsrq works in that situation. > Do you get any kernel messages when the networking dies?

Sometimes, I get a "spurious 8259A interrupt: IRQ7" or " spurious 8259A interrupt: IRQ15" message on console and syslog, though. > What are the messages you get from xircom_tulip_cb when it gets > initialized? [make sure you look at dmesg's output, some syslog > configurations don't log all kernel messages.] I stopped pcmcia, unloaded all modules, and reloaded them again.

This looks like the notebook simply stops answering, after which the remote side fills up the window and then waits, arping for the notebook after running into a time out. > > 2.4.13-ac5 has the patched xircom_tulip_cb from 2.4.13-pre3? > > It does. Then there is still a bug. Or something's wrong here. I cannot rule out that my notebook is broken, Chicony has a history of making abysmally bad hardware, and the machine is about two years old. I don't have a reference notebook that has Linux installed and can do Cardbus to cross-check, sorry.
