I am trying to help the bcm43xx project develop a driver for the
Broadcom 43xx wireless chips, using my Linksys WPC54G card.
Unfortunately, since the group got far enough to turn on RX DMA, my
system has frozen whenever I load the driver. TX DMA was OK. It seems to
correlate with the receipt of a beacon from my AP, but that cannot be
proven. When the freeze happens, I cannot do anything more and have to
power the system off.
What should I consider as a cause of the freeze? I have reviewed the
code and do not find any obvious out-of-bounds memory references. I have
tried various 'printk' statements, but none of them in the bottom-half
interrupt routine make it to the logs. Are there any tricks that I
should try?
Thanks,
Larry
