Hi,
Network down often and ksoftirqd0/1 take 100% of CPU.
I'm using a netgear wpn311 wireless PCI adapter.
lspci -v

dmesg

when the problem occurs, dmesg return this message:
wifi0: rx FIFO overrun; resetting
wifi0: ath_reset: unable to reset hardware: 'Hardware didn't respond as
expected' (HAL status 3)
I do "/etc/init.d/network restart" to resolve the problem, network restart
and ksoftirq returns to sleeping mode.
This problem happens 5 to 6 times during the day.
This is the same problem that this ticket: http://madwifi.org/ticket/1835
