I have a Soekris net 5501 and a ral RT2860/2850 PCI card (dmesg below). B While trying to use the system for an access point, I discovered a way to consistently cause the system to hang. B (Note: This is *different* from a similar, now fixed, system hang that I reported circa 4.6-beta).
To cause the system to hang, put ral0 into HostAP mode, connect a computer with an FTP server to one of the Ethernet connections, then connect another computer to the wireless access point and attempt to download a largish file over FTP. B The system will hang within 15 seconds from the start of the transfer. Using FTP is not required, any "heavy" traffic will cause a similar result, but the hang only occurs when ral is in hostAP mode. B/c the previous hang I discovered has since been fixed, I do not think this is a hardware problem. B I'd like to work with someone who knows more about this to try and pin down the source of the problem so that it too can be fixed. B If this problem is specific to this ral model, I have no problems ordering a different, working one and giving this one to the appropriate developer so that it can be debugged from there. B Similarly, if there is a concern that this *is* a hardware problem, I'll be happy to purchase a "known good" ral or similar wifi card and test it under similar conditions (provided someone can direct me to one). Also: *Using or not using wpa doesn't change anything *Using 11a or 11g does not change anything *The power supply is not an issue; I'm using the largest one from Soekris and have tried half a dozen different ones. B All get the same hang. *I couldn't get the console to give me ddb access after the hang, so I tried sending it a break before and then "c". B I get that far, but when the system hangs ddb is unresponsive. For reference, the hang from 4.6-beta was a caused by sending traffic between two of the vr ethernet ports while ral was up and in HostAP mode. B That hang no longer exists, but if someone wants to look at it for comparison, my emails are http://marc.info/?l=openbsd-misc&m=124685949929721&w=2 and http://marc.info/?l=openbsd-misc&m=124697898624989&w=2 Thank you for any help you can provide. --Max H.
