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

Thank you for any help you can provide.
