I have this PCMCIA card: PMX PE-200, which uses the "ed" driver. It has worked for me before on another system, but in trying on a ThinkPad A20m laptop with FreeBSD 4.1.1-REL, it seems to temporarily "freeze" the system when plugged in. That is, if pccardd is not running, everything looks normal. When pccardd is started, it detects the card and the kernel spits out the probe message with the IRQ and memory address, and then the system completely freezes: pccard: card inserted, slot 0 ed0 at port 0x300-0x31f iomem 0xd4000-0xd43ff irq 10 slot 0 on pccard0 Pressing keys on the keyboard does nothing. But then if I pop out the card, the system continues normally (responding to any keys pressed while frozen), printing out the card's Ethernet address, etc. Of course then pccard immediately detects the card has been popped out and detaches the interface: ed0: address 00:20:e0:0f:a6:9f, type NE2000 (16 bit) ed0: detached pccard: card removed, slot 0 stray irq 10 This can be repeeated any number of times. Any ideas? I've tried different interrupts, etc., to no avail. This card works fine under Win98 on the same laptop.
