[rt2x00-users] rt2800usb stops working with big file transfers in AP and IBSS

[Juan Carlos Garza]

Hi Helmut,

Thanks a lot for your help!

I applied the patches (manually), and tested the stick.

The transfer of big loads now is successful. The
"rt2800_txdone_entry_check:" warnings are still there, but they are
less frequent (just like in the example i gave you with the laptop
where it succeeded with the unpatched driver), some 5 warnings every
1, 2 or 3 seconds.

I was able to transfer a 512 MByte file from a Linux 2.6.24 system
running an Intel Atom processor with a rt3071 USB stick to the
follwing NICs:

Intel 3945ABG running Windows XP 32 bit
Realtek rtl8188cus running on Windows XP 32 bit
Dell 1397 running Windows 7 64 bit
Broadcom 4306 running Linux
Intel 4965 running Windows XP 32 bit
Ralink rt3070 running Windows XP 32 bit.
Atheros AR9170 running Windows XP 64 bit and 32 bit.

Once again, thanks a lot for your support, and I'm glad to be able to
test the experimental patches.

Best regards,

Juan Carlos
