On the minus side we still have trouble bringing up all the interfaces
on second boot and later. So I've filed a bug on it, and am
making the firmware available for all and sundry to suffer with
on this crisp/clear sunday.


And I can blow up the driver still with the rrul test

[ 1024.917968] ath: phy0: Failed to stop TX DMA, queues=0x00e!
[ 1028.972656] ath: phy0: Failed to stop TX DMA, queues=0x00e!
[ 1332.210937] ath: phy0: Failed to stop TX DMA, queues=0x00e!

but so far, not with the rrul_unclassified test.

Lastly download performance under rrul has become dismal for some reason
since last I tried it (about august on 2ghz)

On the plus side, sebastian's latest AQM changes made it in under the wire
with (no kidding) 30 seconds to spare, and I can't crash the gui anymore.

I'm going to go see the hobbit. My money's on smaug for roast dwarf.

Bug #437: bug in initializing wifi interfaces

Author: David Taht
Status: New
Priority: Normal
Target version:

Since about cerowrt 3.10.18 there has been a bug in initializing the
wifi interfaces.

It looks like a set of race conditions in netfd. On initial boot
(while competing with a jffss init,
it generally does better in bringing up more interfaces) but on the
second boot, it's anybody's guess as to what will come up.

(there is a similar problem in starting dnsmasq)

The problem persists in cerowrt 3.10.24-4 which is built from openwrt svn 39076
