Description Dmitry Ilyin 2008-03-03 12:34:55 UTC

I have problems with madwifi-ng and recent kernels. When i switch my card to master mode (wlanconfig ath0 create wlandev wifi0 wlanmode ap) after two system completely hangs.
It happened on two of my boxes amd64 and x86.
Problem appears with kernel (gentoo-sources) 22+ and madwifi >= 0.9.3.3.
Downgrading to earlier releases helps.
I also compiled CVS version of madwifi (0.9.3.5?) on 23 (amd64) kernel an it did not hang and worked but writes to syslog (i filtered it away)
"Virtual device ath0 asks to queue packet!"

Even if it works sometimes ksoftirq/0 begins to eat 99% of CPU which can be stoped by "ifconfig ath0 down".

Madwifi now makes a lot of problems. It worked flawlessly several months ago ((

Reproducible: Always

Steps to Reproduce:
1.install madwifi-ng and use master (host AP) mode
2.
3.

Actual Results:  
system hangs

Expected Results:  
madwifi work without problems as it was before.

I tried pci wifi cards DWL-510(AirPlus) DWL-520(XteremG) DWL550(Air Premier).
I do not use turbo mode.
