Hi,
I'm trying to install an usb based wlan stick; yet whenever I connect it to my machine I get drowned by kernel messages, hundreds per second: | Quote: | Apr 22 19:35:52 linux kernel: [ 1312.627987] usb 1-8: link qh0-00ff/ffff88003b9e3600 start 0 [2/0 us]

at first I thought it was some debugging feature in kernerl driver configurations (atheros chipset), but couldn't find anything related.
Hints anyone?
Thanks

| Code: | | grep DEBUG /usr/src/linux/.config |

True! here's the culprit: | Code: | grep DEBUG /usr/src/linux/.config | grep -v not
