Comment 5 for bug 190515

I have the same problem on Hardy Alpha 3 and Alpha 4 (can't remember earlier). This doesn't happen in Feisty and Gutsy.

However, I installed 64-bit Debian Sid and there is no slowdown at all. I even get 54Mbps instead of typical 11Mbps (!) over WPA-protected access point.

I have built rt2500-source twice:
* 1:1.1.0-b4-3 for 2.6.21-2-amd64 kernel
* 1:1.1.0-b4+cvs20070924-3 for 2.6.24-1-amd64 kernel

Details follow:
