Summary: Libertas SDIO / Network - transmit timed out

Details:

Hello,

I did not work on my CM-BF548 board for quite some time now as I had

other things to do.

WLAN worked OK last time I tried it - very stable and no problems at all.

That was with Revision 6050 from 2009-02-03 of the Linux Kernel.

This Morning I did a full SVN Update with latest revision and I can still connect to the WLAN AP,

open several telnet sessions, ping etc. but always when I do any "larger" data transfer

(running top in a Telnet session is enough)

I get a timeout and the connection gets lost!

Doing the same (and big Data Transfers) with normal LAN works just fine.

So far so good.

.... now I do some data transfer via Telnet.

Works for a short time but then:
