Hi Ivo, I recently obtained an rt61pci NIC, and in an attempt to find out whether my recent hostapd problems were rt2500pci specific (remember that?) I plugged it into the server. the interface goes up well, but I get an oops as soon as I run hostapd, seems something with debugfs. This shows up in dmesg, let me know if you need any more info. best regards, Bas attached: dmesg, modinfo, lspci dmesg ----------------------------------------------------------------- Unable to
