Package: linux-image
Version: 4.19.28-2
The ath10k 802.11 driver reads the country code for the radio regulatory domain from the ACPI table.
If it can't get a valid value it locks to US regulatory domain which is wrong for most countries.
This makes Atheros devices in master mode unusable on ACPI devices in most countries.
Sven Gottschall suggested on ath10k mailing-list to return -EOPNOTSUPP in function
ath10k_mac_get_wrdd_regulatory(struct ath10k *ar, u16 *rd) in file drivers/net/wireless/ath/ath10k/mac.c to solve this.
static int ath10k_mac_get_wrdd_regulatory(struct ath10k *ar, u16 *rd)
{
return -EOPNOTSUPP;
}

Renne
