[Bug 544752] Re: WARNING: at /build/buildd/linux-2.6.32/drivers/net/wireless/ath/ath5k/base.c:1142 ath5k_tasklet_rx 0x53b/0x5a0 [ath5k]()

[brainstorm]

"Side"-simptoms:
While using skype there are hiccups on the calls every 1-2 minutes (that happened on Ubuntu 9.10 too).

It does not happen when I compile and use the "old" hal/madwifi-ng
driver (neither on 9.10 nor 10.04) :-/

lspci -v:
