Hallo,

RaLink has written a kernel module as a driver for the WiFi cards
(mine is a miniPCI from MSI) using their chipset RT2560. People using
their module (source available at
http://www.ralinktech.com.tw/drivers/Linux/RT2500-Linux-STA-1-4-0-0.zip,
but not GPL) on kernels 2.6.6 and upwards, experience very bad
performance, maybe because of tons of warnings found in
/var/log/messages, as in subject eg:

Badness in local_bh_enable at kernel/softirq.c:136

I would like to know if this warning is caused by an error in the
driver, and if so, what we should be looking for.

Thanks for any advice,

Gerard
