Comment (by papaj0e):
And once again my wireless gets broken at '00000 boundary:
{{{
root@OpenWrt:~# cat /proc/interrupts

4: 11627373 MIPS eth0

}}}
Which makes exactly 11400000 interrupts (127300000-115900000) before the
crash.
I guess my next crash is going to be at 138700000 interrupts
(=127300000+11400000).
Here is the log:
