I have already reported on linux-wireless (short: l-w) ML that after especially the merge of "AHB Bus support" patchset (see [2]) my ath5k was not working as expected in daily use (also modinfo). I am not sure if it is the driver but reverting the 9 commits in my local linux-next GIT seemed to "stabilize" a bit the Internet connection. The patchset from Nick (see below) definitely helped to stabilize ath5k. What means "daily use"? Quassel IRC-client (around 20 channels), Iceweasel (Debian's answer to firefox) with sometimes 20 tabs open and radio live-stream in VLC. Here and there I have still audio-dropouts or when typing emails in web-based email-service, it stalls when "stressing" with for example parallelly creating a tarball (that's normally no huge workload) the probability for audio-dropouts increases. As I said I am not sure what is causing these hangs, it's ath5k driver? Is it sth. else? How to dig into it? Unfortunately, modinfo does not list aliases with pci-id matching (I have already reported to l-w ML, see below). With reverting "AHB Bus support" patchset modinfo works as expected. As a workaround I added ath5k to /etc/modules (see below), otherwise I have to stop networking, unload + reload ath5k and start networking again. I also added an iw station dump (see below) and outputs of filtered lspci and dmesg commands. Not sure if this is helpful to mention, I use crda and wireless-regdb (see below). BTW, I have these two patches in addition to linux-next: (+) OK mac80211-fix/mac80211-fix-a-compiler-warning.patch (+) OK ath5k-fix/ath5k-Use-capabilities-information-for-the-number-of-TX-queues.patch Any ideas/help appreciated, Thanks in advance.
