Having tried the below-mentioned patch, I'd say this should pose no problems. The location of the PCMCIA slot (id-wise) shouldn't change as far as I understand; and yes, it only has one of them. As long as nothing changes with regard to the sys filesystem, we should be OK with these rules even in case of a NIC replacement. The patch applied cleanly on udev-110 + udev-111 (although I did only test it running on udev-110 - works fine there). > I had a preliminary by-path patch for udev somewhere, let me see if I > can find it...

By observation, it seems that the NICs we use in the PCMCIA slot appear to the kernel as a PCI device. lspci for the card in PCMCIA slot: 04:00.0 Ethernet controller: Abocom Systems Inc RTL8139 [FE2000VX] CardBus Fast Ethernet Attached Port Adapter (rev 10) I don't know about "all NICs plugged to PCMCIA slots", but the ones we use(d) all behave(d) that way. > If I knew how those devices showed up in sysfs, I could > probably add it (otherwise you could just treat this patch as a starting > point). Regarding the extension towards PCMCIA-slotted NICs, I can give you no interesting information, as it works right without any changes in our case. There isn't even an entry under /sys/bus/pcmcia on the laptop. greets, Jens PS: thx for the patch, fine thing, that -- [EMAIL PROTECTED] 23.....56.......drifting By caffeine alone I set my mind in motion, By the beans of Java do thoughts acquire speed, hands acquire shaking, the shaking becomes a warning, By caffeine alone do I set my mind in motion -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
