Hi Ivo, first of all, thanks a lot for your help so far, I feel I'm getting really close to making rt2500pci work as an AP with hostapd:) As I've told you in previous emails, hostapd hangs somewhere during the authentication process, just after receiving the EAPOL-Key frame. After hostapd outputs: WPA: 00:1b:77:a4:db:26 WPA_PTK entering state PTKCALCNEGOTIATING2 WPA: 00:1b:77:a4:db:26 WPA_PTK entering state PTKINITNEGOTIATING it hangs, and wlan1 has received exactly one frame from the laptop (there's a message showing up in the logs at this time, complaining that wlan1 can't find any IPv6 routers). No further frames are sent from hostapd, although beacon frames are still being sent, and the interface still receives frames as well. The last frame rt2500pci receives, is the EAPOL key from the laptop. Only ctrl-c can kill hostapd, and after that the driver is in an unusable, and unstable state, even unloading rt2500pci, does not help, and eventually the entire system will become unstable, in particular under high I/O loads. After some time, a message shows up that the IRQ for the rt2500pci is being disabled ( ACPI: PCI interrupt for device 0000:05:01.0 disabled). If after that, I get a lot of I/O activity on devices sharing the same pci interrupt ( like recording some TV with an ivtv card) then a lot of shit happens, ivtv gives time outs, harddrive controllers give I/O errors, etc. As I've mentioned, this also happens after I unload+reload the rt2500pci module. So, apparently the hardware is left in a bad state after hostapd locks up. Johannes, in the meantime, has tested hostapd again for current wireless-testing, and for him things work (on a b43). His guess, also based on the fact that the entire system gets unstable, is that something still goes wrong in the rt2500pci driver. Do you have any suggestions as to what I can do to further debug this issue? I've made a register dump, as suggested on the serialmonkey forum, it's attached to this mail. I've also attached an archive with a frame dump from debugfs, obtained during the authentication process leading up to the hang. The archive also contains the hostapd and interface configuration files, and a log of the hostapd output. Well, I hope you can help me a bit further on the basis of this information, if there is anything else I can do to debug this issue further, then please let me know. thanks in advance, and best regards, Bas
