Hello,

today, I had to switch to openSuSE 11.3 because of end of life of 
openSuSE 11.2.

I thought, that this would be a small thing, because I used the same 
kernel in 11.2 as in 11.3 (both times 2.6.34.9-7-desktop): openSUsE had 
for 11.2 the same kernel additionally. The only difference between them: 
the kernel for openSuSE 11.2 was compiled with gcc 4.4.1 (gcc 4.4 branch 
revision 150839) - the kernel for openSuSE 11.3 is compiled with gcc 
4.5.0 (gcc 4.5 branch revision 160292).

With the gcc 4.4.1-compiled kernel, the "rt2800pci_txdone: Warning - Got 
TX status for an empty queue 0, dropping" came up rarely (but it came 
up, too), with the gcc 4.5.0 compiled kernel, this warning comes up 
after a few seconds of sending data with netperf (throughput is > 10 
MB's) and 45 times(!). The connection is dead after that storm!

If you do not have this problem - which gcc do you use or which options 
do you use for compiling?


Kind regards,
Andreas
