ioctl[PRISM2_IOCTL_PRISM2_PARAM]: Invalid argument

Thu Feb 17 15:23:31 PST 2005

When I start hostapd it generates the following error:

alpha:/usr/src/hostap-driver-0.3.7# hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
ioctl[PRISM2_IOCTL_PRISM2_PARAM]: Invalid argument
Could not enable hostapd mode for interface wlan0
hostap driver initialization failed.
rmdir[ctrl_interface]: Bad address

hostap_pci driver is working correctly.

I have attached an strace, but can't see anything special why this
problem occurs. Kernel version is 2.6.8, but 2.6.10 also generates the
same problem.

The card has functioned fine (with hostapd), in a different computer.

Kind regards,

Marc
