[Bug 341952] Re: system freeze/crash in jaunty - "ath5k phy0: unsupported jumbo/ath5k phy0: noise floor calibration timeout"

[gene]

Hi Leann,
I installed backport modules a couple days ago. Since then no system lock-ups so far.
However, I noticed somewhat worse performance of wireless. Sometimes, when I try to connect via ssh/sft/http I fail. But when switching to the ethernet- everything goes smooth again.
I also started seeing my "favorite" entry in the kernel log:
