#21594: Atheros WNDR3800 - WiFi regression
-------------------------------------+-------------------------------------
Reporter: raz123 | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Designated Driver
Component: packages | (Trunk)
Keywords: dma mac beacon r48234 | Version: Trunk
dd wifi |
-------------------------------------+-------------------------------------
CC on r48225 is fairly stable.
DD on r48234 is unstable. In fact, WiFi on DD branch has been mostly
unstable for me. Here are the relevant logs that I captured on DD r48234.
Let me know if more is needed. PS: I am unable to build, so testing on my
side is done with the daily builds and/or community releases.
