Bug#456804: rt2x00-source: Connection stops working after a while under load

[Ben Hutchings]

I apologise for being slow to respond to this bug report.  It was
received from the address <local at bottlenose.demon.co.uk>, which I assume
to be invalid, so I took the above addresses from
www.bottlenose.demon.co.uk.  Please let me know which address I should
use for further messages.

This is a known bug that should be fixed in later versions of the
driver.  A fixed version of the driver is included in Linux 2.6.24.
Please try installing that, if you can.  I am still working on an update
to rt2x00-source for use in 2.6.22 and 2.6.23.

Ben.
