This is a firmware bug. Can you please take the contents
of /sys/bus/platform/drivers/wl12xx_driver/wl12xx/fwlog and send it to
us so we can take a look at what's going on?
Sorry, it isn't a firmware bug. It was a configuration problem on my
part. The defconfig
file I was using was enabling a TVOUT driver which this board doesn't
have. When
the driver wanted to blank the screen, it was turning off my slow clock
to my WL1271.
When the WL1271 later becomes idle, it goes into a low power state which
depends upon
slow clock. So please tell your firmware guys, "never mind."
Okay, cool that you found the reason for the problem. :) I thought it
was a firmware problem because all the symptoms show that the chip
stopped responding. :)
wl12xx: Hardware recovery in progress. FW ver: Rev 6.3.0.0.77 pc: 0x23923
This tells us where the PC was when the crash happened. I'll ask our
firmware team to analyze this.
"Never mind...."
Cool!
Now, Gary, do you still have the same (or a similar) problem with your
setup?
Yes, I still have issues. One problem is that the wlan interface will
not come up unless I manually perform a scan. If I just do this to
bring it up (my AP uses WPA2)
# ifconfig wlan0 hw ether D4:94:A1:8E:1E:17
# ifconfig wlan0 up
ADDRCONF(NETDEV_UP): wlan0: link is not ready
# ifup wlan0

I'm using the 2012-02-28 snapshot of compat-wireless, my kernel is 2.6.37
Ideas?
