next in thread | raw e-mail | index | archive | help
I have a problem running the Atheros AR5414 wireless mini-pci-card
(Compex model WLM54AGP23) with FreeBSD 6.3-RELEASE (GENERIC i 386) on a
Soekris 4521.
I get lots of messages:
"interrupt storm detected on "irq10:"; throttling interrupt source"
and
"ath0: device timeout"
And after sometime the interface stops functioning.
Anybody any suggestion?
Thanks,
Huub
