Problems using the libertas

[Kalkere, Giridhara(IE10)]

Dan, 

Thanks for the reply.

We are using the firmware 9.124.3p37.

Please let us know what is the latest firmware version available for the SD8686 on SDIO interface and also where can I look for the latest firmware?

If any patches available for the libertas driver please let us know.

Thanks and Regards,
Giri

Typically this is a firmware crash.  What firmware version is the 8686 using?
