Hi Dan,

[MV] Do you have an approximate idea of what release the failure started occurring?

[MV] I'm not sure if it is related to the problem you're seeing, but I see that you're using a 5300, so can you try to load the iwlwifi module with the following parameter and see if it helps?

modprobe iwlagn bt_coex_active=0

Thanks,
Meenakshi
