Description Jurgen Kramer 2006-01-25 19:39:10 UTC
Description of problem:
Transferrate drops or complete stalls due to firmware resets. Occasional
'unknown notification' errors

Version-Release number of selected component (if applicable):
kernel 2.6.15-1.1861 - 1863

How reproducible:
Always after generating IP traffic, say 'yum upgrade', over the wireless link.
Dmesg shows ipw2200: Firmware error detected. Restarting. Numerous times.
Transferrate drops or stalls as a result. 

Steps to Reproduce:
1. Generate some IP traffic over the wireless link
2. Transferrate drops or completely stalls
3. Check for errors with dmesg
  
Actual results:
Transferrate drops or completely stalls

Expected results:
No firmware resets, no tranferrate degradation of stalls.

Additional info:
firmware 2.4 from Sourceforge ipw2200.sf.net. Configured with 128-bit WEP.
The firmware restarts seem to be happening since ipw2200 driver > 1.01 (or
version included in FC4 kernel).

Occasional 'Unknown notification' errors look like:
ipw2200: Unknown notification: subtype=40,flags=0xa0,size=40

I have the same problem in FC4 with testing kernel 2.6.15-1.1823.

Comment 3 Anton Keks 2006-01-28 12:10:39 UTC
If a download just stalls, no more connections work after that, but network
device restart helps.

Sometimes a stalled download in accompanied by the fact that ksoftirqd starts
eating 100% cpu, and this problem can only be "fixed" only by restarting the system.

Comment 4 Anton Keks 2006-02-15 19:44:49 UTC
This bug shows up in FC4 with all the latest updates, so probably the version
above should be changed to 'fc4' and priority to 'high'?

Comment 5 Dave Jones 2006-02-19 02:35:16 UTC
Jurgen, does the kernel from
http://people.redhat.com/davej/kernels/Fedora/devel/ fix this for you ?  John
merged a fix recently that may solve this problem, but due to the test3 freeze,
I don't think it made it to rawhide yet.

Anton, the same fix has been merged in FC4 CVS, and will go out in the next
update soon.


Comment 6 Jurgen Kramer 2006-02-20 17:20:13 UTC
OK, I've tried the devel kernel from feb. 19th and used my wireless link to do a
yum update. After downloading about 650Mb over the wireless connection still no
firmware resets! So for now it seems the bug is gone.

Thanks.
