Warning: Change in kernel (2.3.99-pre3) causing problem with cardmgr. 

Forum: PCMCIA driver development

From: Brian Mays brian

There is a change in the kernel somewhere that is causing a problem: if 2.3.99-pre1 is used things work correctly, but when 2.3.99-pre3 is used cardmgr does things wrong.

Looking at the 2.3.99-pre3 patch, it is apparent that driver has been modified to use the new PCI scheme. I think that this is causing the problem.

Here are the relevant parts of the syslog. In this example, the user is trying to use a network card. Note that "network start 3c575_cb" is run by cargmgr instead of "network start eth0".
