RE: mwifiex crash when removing interface while scanning

Hi Daniel,

We are now also seeing cmd_pending warnings in testing at Marvell in Santa Clara.  Bing is working on a revised patch for this issue.  We'll keep you posted on the progress.  I'll also update the tracking system ticket #479039.

Thanks for continuing to look at this.

Unfortuntaely the cmd_pending warning is still there and the numbers are now -4 and -5 e.g.
[  128.269912] mwifiex_sdio mmc0:0001:1: rx_pending=0, tx_pending=0,
cmd_pending=-5

This is using the same test script used in the opening message on this thread, with uap0 and p2p0 auto-creation disabled, with or without NetworkManager running at the same time.

Thanks
Daniel
