libertas: tx watch dog timeout

[Wright, Alexander]

Here is more detailed info on my kernel and the error message:
(sorry for double posting)

Hello, I have the openembedded distribution installed on a microsd card as explained here:
http://wiki.gumstix.org/index.php?title=Verdex_Git_Repository

The hardware is a gumstix verdex-pro XL6P inside an acroname garcia robot.

I have intermittant wifi problems with the libertas wireless module with the 2.6.31 kernel that I didnt experience when running 2.6.21 off the jffs2 filesystem.

This is the kernel module version info according to opkg:
kernel-module-libertas - 2.6.31-r0.5


The error is as follows:

Hello, I have an acroname garcia robot with a gumstix verdex-pro 600mhz board.
(http://www.gumstix.net/Hardware/view/Hardware-Feature-Overview-Sheets/Gumstix-Verdex-Pro-Feature-Overview/112.html)

I am running into the following problem using the "wifistix" marvel 88W8385 module with the latest openembedded kernel / filesystem
http://old.nabble.com/-verdex--libertas-wifi-driver-hangs-td28842840.html

The wifi on the original kernel / file system work fine, but I need to reinstall everything to run off a microsd card for more disk space. Is this a firmware problem? If so where can I get a recent version of the firmware and how do I install it onto my openembedded machine?

-Thanks
Alex Wright
