I had this problem when I used the .sys file included with the Windows driver package instead of mgmt.o from the linux driver package. Which are you using?

I mostly got a good download rate of 25K/s working under mandrake 9.0. I am a 'lite' users of adsl under ISP xs4all so I get no more than that. In cases this rate was far less, I guessed that this had to do with a 'weakest link' being somewhere. The CRC-errors in AAL5-frames are very often present on my system too. Sometimes a stop of the adsl connection (killal pppoa3, killall pppd), followed by a restart (pppd call adsl) some moments later (no microcode is realoaded) would make things healthy again and the CRC errors would stay away. But I have not experimented and so can't contribute to the solution of your problem. I am very anxious to what answers you get.
