Yenta, Xircom and resources

[Jan Kasprzak]

	Hello,

	it seems there is some problem with Linux kernel running
on my Compaq Armada M700 with Xircom RBEM-56 ethernet/modem card.
LEDs on the cards go off). Removing the card from the cardbus socket
and inserting it again usually results in the resource allocation
error (messages below). About once of 10 insertions the card starts
working again.

	It _may_ also be a hardware problem (such as overheating). But in The
Other Operating System(tm) it works flawlessly. Another observation is that
when the laptop is connected to the docking station, it works as well.

	Here is the relevant part of /var/log/messages
(2.4.0-test1-ac<something>, but in -test2 it looks similar). It looks
that the cardmgr (or someone else) decides that the bus/socket is
no longer available, and shuts the socket down (the cb_disable(),
cb_release() etc messages).

	Any ideas on what's going on here? Thanks,

-Yenya
