Since the ath5k driver was included in 2.6.25-rc* I've tried it several times,
but the driver seems pretty unstable in keeping the wireless connection to my router.
Machine is a HP NC6000 Laptop with built-in AR5212 wifi card.
lspci reports:
2:04.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)

After modprobing ath5k, dmesg reports with 2.6.25-rc6:

Everything is OK and I'm connected. 00:50:18:3b:2b:04 is my router.
Around 2-5 minutes later the driver suddenly disconnects and syslog reports the following messages.
Since then, ath5k will not reconnect any longer to the router.

On the other side, with a Prism54 wifi cardbus card everything works 100% reliable with the same kernel:
PCI: Enabling device 0000:03:00.0 (0000 -> 0002)

Any ideas ?
