When the router (Linksys WRT160N) operates in 'Mixed' mode (e.g. the N-mode is enabled) the ath9k causes the system to freeze completely after several seconds (sometimes after several minutes) of traffic activity. I tried in both the wide-channel (40MHz) mode and standard channel mode.

I cannot see any logging or crash reports. Keyboard leds are not working so this is a hard lockup.

When the router operates in G-only mode the driver seems to work properly, although I get in the syslog the following events:
"ACPI: EC: GPE storm detected, disabling EC GPE"
"ACPI: EC: missing confirmations, switch off interrupt mode."
