Thus: Hostap 0.3.9 under kernel 2.6.12 works fine with the D-Link DWL-650. Hostap 0.4.4-kernel, included with kernel 2.6.14, does not work; nor do versions 0.3.9 nor 0.4.1 compiled separately against 2.6.14. There seems to be a problem with interrupt delivery. Soon after the module is installed, keystrokes and all other interrupt-driven activity pause periodically for a LONG time (on the order of five seconds). Keystrokes will often auto-repeat because the key-raise interrupt gets delayed and the kernel thinks the key is still down.
