Description ericm24x7 2007-04-11 22:31:10 UTC
Description of problem: Athough the wireless device remain functional at all times, the dmesg outputs keep displaying the following error messages every a couple of minutes: Apr 11 18:07:01 fiji3 kernel: zd1211rw_mac80211 2-4:1.0: zd_chip_control_leds error -110 Apr 11 18:08:57 fiji3 kernel: zd1211rw_mac80211 2-4:1.0: zd_chip_control_leds error -110 Version-Release number of selected component (if applicable): kernel 2.6.20-1.3056.fc7.x86_64 wireless-tools 1:28-1.fc6 How reproducible: Persistent Steps to Reproduce: 1. download and install zd1211 firmware wget http://kwizart.free.fr/fedora/6/testing/zd1211-firmware/zd1211-firmware-1.3-4.kwizart.fc6.noarch.rpm rpm -ivh zd1211-firmware*rpm 2. bring down the old driver zd1211rw and load only zd1211rw_mac80211 lsmod|grep zd1211 modprobe -r zd1211rw modprobe -r zd1211rw_mac80211 modprobe zd1211rw_mac80211 3. Tested under WPA so turn it on if possible 4. run "rsync" to test network transfer. 5. run "dmesg" Actual results: dmesg output will display the following messages every couple of minutes: Apr 11 18:07:01 fiji3 kernel: zd1211rw_mac80211 2-4:1.0: zd_chip_control_leds error -110 Apr 11 18:08:57 fiji3 kernel: zd1211rw_mac80211 2-4:1.0: zd_chip_control_leds error -110 Expected results:
Comment 1 John W. Linville 2007-04-18 18:01:31 UTC
Odd...looks like the USB accesses for controlling LEDs are timing-out occassionally, probably under heavy traffic. Perhaps there is some missing synchronization in the driver...
Comment 2 John W. Linville 2007-04-19 21:52:29 UTC
Please try to recreate this problem using kernel-2.6.20-1.3096.fc7 or later (should be available by sometime on 4/20). Does the problem persist?
Comment 3 ericm24x7 2007-04-19 23:10:59 UTC
I will test as soon as the kernel 3096 build as soon as it reach my mirror. Right now it doesn't affect the basic functionalities (rsyncing and web browsing) that much and the LED seems to work OK. The effective speed right now is a little slow though: ~800 Kbyte/sec (6.4Mbit/sec). Since manual rate adjustment (iwconfig wlan0 rate 48M) is not functional yet, I will worry about that later. The softmac driver usually have the above rate when it is set manually to 54M, but tend to increase better (~2000 Kbyte/sec) when set to 36M or 48M.
Comment 4 ericm24x7 2007-04-25 16:53:18 UTC
Just tested 3104.fc7. I agree that the problem only show up when using under heavy load; since it only show up when I'm running "rsync" program. It doesn't show up when browsing the internet only. I will closed this now since it doesn't appear to affect basic and critical functions.
