Hmm..
If I configure it as ap, yes:
CPU0
5: 28 MIPS 10100000.ethernet
6: 38912 MIPS rt2800_wmac
7: 204558 MIPS timer
9: 0 INTC 10000100.timer
20: 521 INTC serial
25: 2 INTC gsw
ERR: 0
But if I put it in monitor mode (either via config or iw command)
interrupt counter remains zero. What does it mean?
All done with reboots to reset the counter.

Roman
