Re: [Madwifi-devel] overflow - no xmit buf

[Michael T. <mik...@ap...>]

Does sound like interrupts got disabled and didn't get re-enabled - 
assuming the entire system is still working, beacons are being 
transmitted, etc.  This could happen if something crashed in a non-fatal 
way in some routine that disabled interrupts.  Were there any other 
error messages in the syslog before this?
