I've recently started testing my laptop with Ubuntu's 9.04 alpha 
releases (64 bit version).

$ modinfo ath5k
filename: 
/lib/modules/2.6.28-11-generic/kernel/drivers/net/wireless/ath5k/ath5k.ko
version:        0.6.0 (EXPERIMENTAL)

Since the change, wireless network connections haven't seemed quite 
right.  Throughput and connectivity both seemed to be somewhat 
problematic.  General web browsing was sluggish with many pages either 
taking an extremely long time to load or requiring a second/third 
request to get them to load at all.  Torrents would appear to stutter 
(short bursting downloads followed by fairly long lulls of no 
transfers).  I also noticed frequent network disconnects and reconnects 
even in areas with good coverage and strong signal.

I know the above sounds extremely subjective.  However, since switching 
from the ath5k driver to the ath9k driver overall throughput has been 
vastly improved.  The very same torrents that were stuttering before 
suddenly held consistent activity with throughput 2-3x what had been 
seen at any point with the ath5k driver.  Web pages are no longer 
sluggish in loading, nor do they require more than one request.  And I 
have yet to see a disconnect and reconnect in well covered areas.

What I'm wondering is how I can go about gathering useful information 
about the problematic performance I'm seeing for the ath5k developers?
