 |
|
I have an small but anoying problem.
My pcmcia socket is working, even hotplug works with my Netgear wifi card (that's only pcmcia card I have), but there is something strange thou.
If I start Linux with the card in the pcmcia-slot, everthing works fine. But when I insert it while the laptop is already running, Linux doesn't take notice of the card in any way and the powerled of the card stays off. But if I eject it and insert it again, Linux all of a sudden does see the card, loads the modules and everything.
If I eject the card again (mind you, it's running at this time), dmesg shows an eject message (as expected) and the modules are kept running (also as expected). But the strange thing is, when I insert it again, then again nothing happens (no messages in dmesg, powerled of the card stays off). I repeat the procedure of ejecting and inserting, and surprise surprise, the card works again... 
I'm not really sure if this is related to hotplug or acpi. Because the powerled stays off, I would think it's related to the acpi... But then again, I thought acpid used hotplug to test if there's a card inserted...
Who can help me on this? It isn't critical, because the second time the card is inserted, everything works ok, but it's damn anoying... |

Isn't actually powering the card on insert normally done purely by hardware?
Do you have pcmcia-cs installed?

I would think so... I have pcmcia-cs installed (if I remember correctly... I don't have the laptop at hand at the moment).
The thing is, that it can't be a pure hardware problem, because if so, the problem should also occure in windows, but it doesn't.
I think it has something to do with the ACPI-handling in my laptop, because ACPI is also responsible for powering down the pcmcia-socket when a card is present.... |
